We study spin-S Ising models with p-spin interactions on the one-dimensional chain and the two-dimensional square lattice. Here, S denotes the magnitude of the spin and p represents the number of spins involved in each interaction. The anal...
Glassy dynamics in a glass-forming liquid: A first-principles study of toluene [0.03%]

The microscopic understanding of the dramatic increase in viscosity of liquids when cooled toward the glass transition is a major unresolved issue in condensed matter physics. Here, we use machine learning methods to accelerate molecular dy...
Self-consistent theory for sound propagation in a simple model of a disordered, harmonic solid [0.03%]

We present a self-consistent theory for sound propagation in a simple model of a disordered solid. The solid is modeled as a collection of randomly distributed particles connected by harmonic springs with strengths that depend on the interp...

Fracture propagation is highly sensitive to the conditions at the crack tip. In heterogeneous materials, microscale obstacles can cause propagation instabilities. Macroscopic heterogeneities modify the stress field over scales larger than t...
Optimizing search processes in systems with state toggling: Exact condition delimiting the efficacy of stochastic resetting strategy [0.03%]
在具有状态切换的系统中优化搜索过程：精确界定随机重置策略有效性的条件

Will the strategy of resetting help a stochastic process to reach its target efficiently, with its environment continually toggling between a strongly favorable and an unfavorable (or weakly favorable) state? A diffusive run-and-tumble moti...
High-dimensional covariance matrix estimators on simulated portfolios with complex structures [0.03%]

We study the allocation of synthetic portfolios under hierarchical nested, one-factor, and diagonal structures of the population covariance matrix in a high-dimensional scenario. The noise reduction approaches for the sample realizations ar...
Mean-field approximation and phase transitions in an Ising-voter model on directed regular random graphs [0.03%]
Ising voter模型在有向规则随机图上的平均场近似及相变研究

Adam Lipowski et al.
It is known that on directed graphs, the correlations between neighbors of a given site vanish and thus simple mean-field-like arguments can be used to describe exactly the behavior of Ising-like systems. We analyze heterogeneous modificati...
Time-inversion of spatiotemporal beam dynamics using uncertainty-aware latent evolution reversal [0.03%]
利用考虑不确定性的潜层演化逆向处理时空束动力学的时间反转

Charged particle dynamics under the influence of electromagnetic fields is a challenging spatiotemporal problem. Many high-performance physics-based simulators for predicting behavior in a charged particle beam are computationally expensive...
Spatiotemporal patterns in coupled reaction-diffusion systems with nonidentical kinetics [0.03%]
具有非相同动力学的耦合反应-扩散系统中的时空模式
Wei-Li Fan,Teng-Kun Deng,Shuang Liu et al.
Wei-Li Fan et al.
Understanding of the effect of coupling interaction is at the heart of nonlinear science since some nonequilibrium systems are composed of different layers or units. In this paper, we demonstrate various spatio-temporal patterns in a nonlin...

The spread of disinformation (maliciously spread false information) in online social networks has become an important problem in today's society. Disinformation's spread is facilitated by the fact that individuals often accept false informa...
