As a function of rotation frequency, we find a variety of order-disorder transitions and pattern-forming states, including density-modulated stripes, partially jammed states, phase-separated fluids, and mixed fluids. When one species has a constant drive and the drive on the other species is rotated at low frequencies, the system switches between different pattern-forming phase-separated lanes including density-modulated stripes and partially jammed states, similar to what is observed for oppositely driven colloids. The lanes tend to align with the net direction of rotation, resulting in a series of order-disorder switching transitions. The transport curves show abrupt jumps up or down at the transitions, which also correspond with changes in the topological order. We find similar switching transitions when both species rotate out of phase with each other. For intermediate driving frequencies, the system becomes increasingly fluidlike and the laning behavior is lost. At high frequencies, however, the system can again exhibit patterned flow when the rotation orbits become smaller than the average spacing between particles. The switching is reduced when a finite temperature is included, but even for temperatures at which the uniform equilibrium bulk system is liquid, the partially jammed state can generate local density enhancements that lead to recrystallization. We demonstrate the pattern-switching behavior for systems with different screened repulsive interaction potentials.","PeriodicalId":20085,"journal":{"name":"Physical review.

Symbolic expressions for the surface correlation functions are available only for very few models, and we here derive such expressions for the general class of dead-leaves models. Within these models, a two-phase pore-solid structure is created by sequentially and randomly filling space with porelike or solidlike grains that overlap any preexisting structure, in the same way that dead leaves fall on the ground. The obtained mathematical expressions are valid for any grain shape, in arbitrary dimension. The results are illustrated with monodispersed spherical grains as well as with a dead-leaves realization of a Debye random medium. In the latter case, the size distribution of the grains is designed to produce a structure having an exponential two-point correlation function. Compared to Debye random media obtained by numerical reconstruction, the dead-leaves structure has an almost identical surface-surface correlation function, but a distinctly different pore-surface correlation function with different average mean curvature of the pore-solid surface. Using the concepts introduced in the paper, we submit a general analytic expression for the pore-surface and surface-surface correlation functions of the Boolean model of interpenetrating grains, valid for arbitrary grains. We also derive general expressions for the surface correlation functions of mosaic structures.","PeriodicalId":20085,"journal":{"name":"Physical review.

Recently, the robustness of these networks under random or targeted attacks has been of interest. One of the strategies to dismantle a network involves identifying and removing articulation points. These are nodes that are critical to the network's connectivity; their removal causes the network to break into separate components. Most real-world networks are not isolated, but interacting, and can be viewed as multiplex networks. Inherent cascading failure within multiplex structures makes the definition of articulation points evading; an articulation point of a single monoplex layer loses this property due to removal by cascading failure within the parent multiplex network. We extend a consistent definition of articulation points and apply it to real and random multiplex networks. Moreover, we find that most of the real networks are vulnerable to the articulation points removal process. Through extensive simulations, we establish criteria for network resilience to this process across different types of random multiplex network models. These include two- and three-layer Erdős-Rényi multiplex networks, two-layer scale-free multiplex networks with varying degree exponents, and hyperbolic multiplex networks.","PeriodicalId":20085,"journal":{"name":"Physical review.

In this work we formulate an open-system perspective on constrained dynamics, where kinetic constraints are interpreted as a balance of information exchange between the system and an auxiliary environment. This viewpoint naturally introduces a quasiparticle number that characterizes the information balance and motivates a revised ETH for constrained systems. Specifically, the eigenstate expectation values of local observables can be approximated by a grand-canonical-like average defined on the energy-quasiparticle-number plane. For the off-diagonal part of local observables, the relevant density of states (DOS) is generalized to the same plane and controls the typical magnitude of off-diagonal matrix elements. The revised ETH accurately describes long-time averages and temporal fluctuations of local observables for both QMBSs and thermal dynamics. Within this framework, scarred dynamics arises from low-DOS regions on the energy-quasiparticle-number plane, where off-diagonal elements are less suppressed and the approximate spectrum-generating algebra becomes more pronounced. Our results provide a unified description of thermalization and QMBSs in kinetically constrained systems.","PeriodicalId":20085,"journal":{"name":"Physical review.

In this contribution, we identify a quantum analog of this distinct sensitivity for 1-degree-of-freedom spin Hamiltonians subject to periodic instantaneous kicks. After detecting quantum signatures of resonances in the participation ratio and in the quasiprobability phase-space distribution of Floquet eigenstates of the perturbed Hamiltonian, we show that eigenstates of the unperturbed Hamiltonian exhibit greater sensitivity against the perturbation when they satisfy a resonant condition. The sensitivity is quantified through the fidelity between perturbed and unperturbed eigenstates. This distinct sensitivity becomes increasingly pronounced as the system size grows. Our findings are supported by numerical results and insights from analytical calculations based on unitary perturbation theory. Since the resonance conditions are set by commensurability with the driving period, this distinct sensitivity may persist in broader classes of periodically driven systems beyond kicked models, providing a preliminary step toward identifying quantum signatures of the classical breaking of resonant tori.","PeriodicalId":20085,"journal":{"name":"Physical review.

In welding, casting, and layer-wise metal additive manufacturing, however, liquid regions can undergo nonmonotonic thermal histories and reach similar undercooling states with different nucleation readiness. Here, an internal activation variable is incorporated into a continuous nucleation description and embedded in an LB-PF solver for dendritic solidification. The variable acts as an effective continuum state for the accumulation, retention, and weakening of prenucleation readiness. Constant cooling, piecewise cooling, low-temperature pretreatment, and high-temperature holding are used to examine the resulting path-dependent nucleation response. The simulations show that different thermal paths lead to different activation states, accepted-nucleus distributions, solid-fraction evolutions, and grain-scale features even under similar later undercooling conditions. The results suggest that time-nonlocal internal variables can help represent thermal-history-dependent nucleation in continuum phase-transformation simulations.","PeriodicalId":20085,"journal":{"name":"Physical review.

We find several classes of behavior as a function of the cross-coupling between counterpropagating DSs, |c_{r}|, by varying the initial conditions for fixed approach velocity. We use three quantities to characterize the resulting behavior as a function of |c_{r}|: (a) the maximum value of the effective amplitude reached during the interaction process, (b) the time interval between the end of the interaction process between exploding DSs and the start-up of new explosions, and (c) the quantity Ψ related to the effective time of interpenetration obtained by integrating the maximum amplitude over time during the interaction. The differences observed by varying the initial conditions can be traced back to the fact that exploding DSs are intrinsically chaotic as a function of time. Therefore, variations in the phase of the initial conditions or, equivalently, in the initial distance before the start of the collisions, can lead to qualitatively different results. Remarkably one of the possible outcomes, which is particularly sensitive to changes in the initial conditions, is partial annihilation of exploding DSs over a range of |c_{r}|. The fact that either the left or the right pulse survives the collision highlights the deterministic character of the dynamics, even though the system is inherently chaotic. However, for all three types of initial conditions studied a unique behavior emerges as the transition to compound states is approached as a function of |c_{r}| for all three quantities used to characterize the results. For example, the quantity Ψ diverges as the critical value of |c_{r}| is approached.","PeriodicalId":20085,"journal":{"name":"Physical review.
