    Some nonequilibrium systems exhibit anomalous suppression of the large-scale density fluctuations, so-called hyperuniformity. Recently, hyperuniformity was found numerically in a simple model of chiral active fluids (Lei et al 2019 Sci. Adv. 5 eaau7423). We revisit this phenomenon and put forward a microscopic theory to explain it. An effective fluctuating hydrodynamic equation is derived for a simple particle model of chiral active matter. We show that the linear analysis of the obtained hydrodynamic equation captures hyperuniformity. Our theory yields hyperuniformity characterized by the same exponents as the numerical observation, but the agreement with the numerical data is qualitative. We also argue that the hydrodynamic equation for the effective particle representation, in which each rotating trajectory is regarded as an effective particle, has the same form as the macroscopic description of the random organization model with the center of mass conservation.

    The nature of the glass transition of supercooled liquids is still surrounded by controversy. The current status of theoretical understanding of the transition is much more like that before the Currie-Weiss theory for critical phenomena in a sense that the full-fledged mean field theory is still not at hand. This, however, does not mean that we suffer from (literally glass-like) stagnancy in the progress. Contrarily, we witness a revolutionary development of the mean-field description of the slow dynamics near the transition escorted by the bona fide thermodynamic transition at a finite temperature. In this review, we start with the introductory discourse of the phenomenology of the glass transition and outline the whole picture of the glass transition which the contemporary version of the mean-field theory envisions. Furthermore, we present the results of our recent numerical study for a randomly pinned liquid, which strongly support the mean-field scenario. This is the first time forever that the true glass state with thermodynamic singularity has been generated in silico.

  29. Shear jamming and shear melting in mechanically trained frictionless particles

    Takeshi Kawasaki, Kunimasa Miyazaki

        2020.3

     More details

    We investigate criticality near the jamming transition in both quiescent
    systems and those under shear by considering the effect of mechanical training
    on the jamming transition and nonlinear rheology. We simulate frictionless soft
    particles undergoing athermal quasi-static shear using initial configurations
    trained with athermal quasi-static cyclic volume deformations. The jamming
    transition density of the initial configuration $\varphi_{\rm J0}$ is
    systematically altered by tuning the ``depth'' of mechanical training. We exert
    a steady shear on these configurations and observe either shear jamming (gain
    of stiffness due to shear) or shear melting (loss of stiffness due to shear),
    depending on the depth of training and proximity to the jamming transition
    density. We also observe that the characteristic strains, at which shear
    jamming or melting occur, diverge at a unique density $\varphi_{\rm JS}$. This
    is due to the shift of the jamming transition density from $\varphi_{\rm J0}$
    to $\varphi_{\rm JS}$ under shear, associated with loss of memory of the
    initial configuration. Finally, we thoroughly investigate nonlinear rheology
    near the jamming transition density, and contrary to previous works, we find a
    nonlinear ``softening'' takes place below as well as above the jamming
    transition density.

    We investigate the dynamics of the randomly pinned Fredrickson-Andersen model on the Bethe lattice. We find a line of random pinning dynamical transitions whose dynamical critical properties are in the same universality class of the A(2) and A(3) transitions of the mode coupling theory. The A(3) behavior appears at the terminal point, where the relaxation becomes logarithmic and the relaxation time diverges exponentially. We explain the critical behavior in terms of self-induced disorder and avalanches, strengthening the relationship discussed in recent works between glassy dynamics and random field Ising model.

    Using molecular dynamics simulation, we investigate the slow dynamics of a supercooled binary mixture of soft particles interacting with a generalized Hertzian potential. At low density, it displays typical slow dynamics near its glass transition temperature. At higher densities, particles bond together, forming clusters, and the clusters undergo the glass transition. The number of particles in a cluster increases one by one as the density increases. We demonstrate that there exist multiple cluster-glass phases characterized by a different number of particles per cluster, each of which is separated by distinct minima. Surprisingly, a so-called higher order singularity of the mode-coupling theory signaled by a logarithmic relaxation is observed in the vicinity of the boundaries between monomer and cluster glass phases. The system also exhibits rich and anomalous dynamics in the cluster glass phases, such as the decoupling of the self- and collective dynamics.

    We use molecular dynamics simulations to investigate dynamic heterogeneities and the potential energy landscape of the Gaussian core model (GCM). Despite the nearly Gaussian statistics of particles' displacements, the GCM exhibits giant dynamic heterogeneities close to the dynamic transition temperature. The divergence of the four-point susceptibility is quantitatively well described by the inhomogeneous version of the mode-coupling theory. Furthermore, the potential energy landscape of the GCM is characterized by large energy barriers, as expected from the lack of activated, hopping dynamics, and display features compatible with a geometric transition. These observations demonstrate that all major features of mean-field dynamic criticality can be observed in a physically sound, three-dimensional model.

    We study the effects of random pinning on the Fredrickson-Andersen model on the Bethe lattice. We find that the nonergodic transition temperature rises as the fraction of the pinned spins increases and the transition line terminates at a critical point. The freezing behavior of the spins is analogous to that of a randomly pinned p-spin mean-field spin glass model which has been recently reported. The diverging behavior of correlation lengths in the vicinity of the terminal critical point is found to be identical to the prediction of the inhomogeneous mode-coupling theory at the A 3 singularity point for the glass transition.

    We use computer simulations to study the thermodynamic properties of a glass-former in which a fraction c of the particles has been permanently frozen. By thermodynamic integration, we determine the Kauzmann, or ideal glass transition, temperature T-K(c) at which the configurational entropy vanishes. This is done without resorting to any kind of extrapolation, i.e., T-K(c) is indeed an equilibrium property of the system. We also measure the distribution function of the overlap, i.e., the order parameter that signals the glass state. We find that the transition line obtained from the overlap coincides with that obtained from the thermodynamic integration, thus showing that the two approaches give the same transition line. Finally, we determine the geometrical properties of the potential energy landscape, notably the T-and c dependence of the saddle index, and use these properties to obtain the dynamic transition temperature T-d(c). The two temperatures T-K(c) and T-d(c) cross at a finite value of c and indicate the point at which the glass transition line ends. These findings are qualitatively consistent with the scenario proposed by the random first-order transition theory.

    We analyze, using inhomogeneous mode-coupling theory, the critical scaling behavior of the dynamical susceptibility at a distance. from continuous second-order glass transitions. We find that the dynamical correlation length xi behaves generically as epsilon(-1/3) and that the upper critical dimension is equal to six. More surprisingly, we find that xi grows with time as ln(2)t exactly at criticality. All of these results suggest a deep analogy between the glassy behavior of attractive colloids or randomly pinned supercooled liquids and that of the random field Ising model.

    We present several theoretical and numerical results which bolster the mean-field scenario of the glass and jamming transitions. The results of the replica theory, the mode-coupling theory, and the simulation results are compared for the hard spheres in high dimensions, the ultrasoft potential fluids, and the jammed systems.

     More details

    A well-known puzzle for researchers working on the glass transition problem is that a static snapshot of a supercooled liquid looks very similar to that of a high-temperature liquid. However, these two systems are very different dynamically, as their relaxation times can differ by fourteen orders of magnitude. No simple signature of this phenomenon is found in particle configurations. What has been understood in the last thirty years is that a clear signature can instead be found by looking at dynamical correlations or, expressed differently, by observing how the dynamical relaxation process unfolds in space and time.

    We investigate the dynamics of the randomly pinned Fredrickson-Andersen model on the Bethe lattice. We find a line of random pinning dynamical transitions whose dynamical critical properties are in the same universality class of the A(2) and A(3) transitions of the mode coupling theory. The A(3) behavior appears at the terminal point, where the relaxation becomes logarithmic and the relaxation time diverges exponentially. We explain the critical behavior in terms of self-induced disorder and avalanches, strengthening the relationship discussed in recent works between glassy dynamics and random field Ising model.

    Using molecular dynamics simulation, we investigate the slow dynamics of a supercooled binary mixture of soft particles interacting with a generalized Hertzian potential. At low density, it displays typical slow dynamics near its glass transition temperature. At higher densities, particles bond together, forming clusters, and the clusters undergo the glass transition. The number of particles in a cluster increases one by one as the density increases. We demonstrate that there exist multiple cluster-glass phases characterized by a different number of particles per cluster, each of which is separated by distinct minima. Surprisingly, a so-called higher order singularity of the mode-coupling theory signaled by a logarithmic relaxation is observed in the vicinity of the boundaries between monomer and cluster glass phases. The system also exhibits rich and anomalous dynamics in the cluster glass phases, such as the decoupling of the self- and collective dynamics.

    We use molecular dynamics simulations to investigate dynamic heterogeneities and the potential energy landscape of the Gaussian core model (GCM). Despite the nearly Gaussian statistics of particles' displacements, the GCM exhibits giant dynamic heterogeneities close to the dynamic transition temperature. The divergence of the four-point susceptibility is quantitatively well described by the inhomogeneous version of the mode-coupling theory. Furthermore, the potential energy landscape of the GCM is characterized by large energy barriers, as expected from the lack of activated, hopping dynamics, and display features compatible with a geometric transition. These observations demonstrate that all major features of mean-field dynamic criticality can be observed in a physically sound, three-dimensional model.

    We carried out the conplehensive studies on the glass transition numerically and theoretically. To overcome difficulties of the conventional glass transition studies, we employed non-conventional models and settings, such as (i) novel model systems, (ii) spatially inhomogeneous systems, and (iii) the glasses out of equilibrium. We successfully showed several novel findings such as the existence of the anomalous glass phase, anomalous dimensional dependence of the slow dynamics,the thermodynamic anomalies in the vicinity of the ideal glass transition point, and the anomalous nonequilibrium phase transition in the parameter space of the shear strain and the density.

    1. 水の物理に関して : (1)水の熱力学・動力学異常について研究を行い、両者が構造秩序変数そのものとそれを隣接分子まで空間的に粗視化したものによりそれぞれあらわされることを見出した。これは、両者の起源がともに局所的な正四面体構造形成に起因していることを強く示唆しており、我々の提唱する2状態モデルを強く支持する結果である。(2)また、水とシリカはともに正四面体構造をとるが、ガラス形成能に関しては、両者は極端に異なる性質を示す。その原因が、水における水素とシリカにおける酸素の空間配列の乱れの度合いの相違からきていることを発見した。2. 液体・液体転移に関して : 亜リン酸トリフェニルにおいて、液体・液体転移の可逆性を初めて明らかにするとともに、ダイナミクスを誘電緩和スペクトル測定により実時間追跡することに成功した。その結果は、我々の提唱する二秩序変数モデルの予測と一致した。3. ガラス転移現象に関して : (1)これまで局所的に安定な構造が未知であった、2成分粒子系において、局所的なパッキング能を定量化することで、隠れた構造秩序構造をあぶりだすことに成功し、温度低下とともに、その構造の相関長が動的不均一性の相関長とコヒーレントに成長することを見出した。これは、過冷却液体の示す遅いダイナミクスの背景に構造秩序の発達があるという、我々の提唱するシナリオを強く支持する結果である。(2)ガラス状態にある物質のエイジング、結晶化について研究を行い、固体ガラス状態において進行する遅い過程が、粒子の連続的な運動ではなく、雪崩的な運動により誘起されることを見出した。さらに、その背景に、粒子間の力のバランスにより自己組織的に形成される力鎖のネットワーク構造があることを見出した。(3)ずり流動下で過冷却液体の粘性が減少するいわゆるシアシニング現象の背景に、液体の構造変化があることを明らかにした。特にずりにより引き延ばされる方向の構造エントロピーが、重要な構造指標であることを発見した。4. 結晶化に関して : (1)水の新しい準安定な氷を発見し、氷の各形成において前駆体として働くことを明らかにした。(2)二つの結晶相への結晶化の競合により結晶化が阻害される原因が、その付近で結晶的な回転対称性の破れの度合いが低下し、そのため界面エネルギコストが上がり結晶核形成に対するエネルギー障壁が上がるためであることを見出した。5. 非線形流動に関して : (1)せん断流れ下にある液体の壁面でのスリップの新しい機構を発見した。(2)高密度な粉体が液体中に分散した系において、その動的な挙動が流体に非圧縮性により大きな影響を受けている証拠を見出した。6. ソフトマターに関して : (1)コロイド分散系の相分離を任意パラメータなしに数値シミュレーションにより再現することに成功するとともに、ドメインの粗大化の新しい法則を発見した。(2)多孔質中の相分離のモルフォロジーを決定する物理機構を明らかにした。(3)コロイドの濃厚分散系に存在すると信じられてきた引力ガラス状態が、実はガラスではなく、空間的な不均一性を持つゲル状態であることを見出した。(4)共焦点レーザ顕微鏡による実験により、ゲル化における運動凍結の起源がガラス化の場合と結晶化の場合があることを明らかにするとともに、それを制御している物理因子を明らかにした。以上のように液体・ソフトマターの時空階層性に関して多くの基本的な問題を解明することに成功した。

    Although the study of the glass transition of the supercooled liquids has a long history but even the mean-field picture has not been completely established yet. In this project, we have implemented extensive simulations and theoretical analysis in order to verify one of the most promising scenario of the glass mean field theory, called the RFOT. More specifically, (1) we established that the RFOT can quantitatively verify the relationship between the glass transition for liquids and the jamming transition for hard spheres, (2) we extended the so-called inhomogeneous mode-coupling theory to the system in the vicinity of the higher order singularity point, and (3) we have done the simulation for a cluster glass phase of the quasi-long ranged "ultra-soft" potential model fluids.

    In this study, we use soft model particles to investigate the "passive system," which is driven by thermal fluctuations or external forces such as emulsions and colloids, and "active system" such as cells and biological species which are self-driven systems. The purpose of this study was to clarify the flow characteristics and vibration properties of high-density passive and active particle systems. As a result, we clarify that the softness of the particles is related to the origin of the complex nonlinear flow phenomenon in the passive system. Besides, we find a new type of non-equilibrium phase transition by using soft particles under periodic shear. In the active system, we develop a new method to extract the vibrational properties of solids by using the linear response between the softness of the particles and the self-driving force.

    In order to understand the essence of the glass and jamming transitions, we investigated the non-equilibrium properties such as the mechanical response ( rheology) to the stress and the response to the nonuniform perturbation such as random-pinning, using the extensive numerical simulations and developments of new theories. Especially for the non-equilibrium properties, we extended the mean-field theory for the new type of the transition called the Gardner transition to the strained system to analyze their rheological properties and confirmed the theoretical prediction successfully by 3 dimensional numerical simulations. As for the random-pinning system, we proved the existence of the thermodynamic glass transition by extensive numerical simulation. On top of these findings, we have also analyzed theoretically the dynamical heterogeneities of the Bethe lattice models and the glass transition of a model systems to which the rotational degrees of freedom are pertained.

    The innovative research area "Synergy of Fluctuation and Structure: Quest for Universal Laws in Non-Equilibrium Systems" strived to expand two major areas of non-equilibrium science; studies of non-equilibrium fluctuations and self-organizing structures. The steering committee supported the collaboration between research groups in our area. We also organized two international symposiums (SFS2015 and SFS2017) and many research meetings.
