We study integrability breaking and transport in a discrete space-time lattice with a local integrability-breaking perturbation. We find a singular distribution of the Lyapunov spectrum where the majority of Lyapunov exponents vanish in the...

We design several examples of constrained, symmetric quantum circuit dynamics that generate nonequilibrium steady states. The qubit networks maintain local memory of the initial conditions and display inhomogeneous subsystem dynamics over l...
Dependence of isochronous bifurcations on the driving-mode phase shift in two-harmonic standard maps [0.03%]

Michele Mugnaine et al.
Some dynamical properties of nonlinear coupled systems can be described by the two-harmonic standard map, a two-dimensional area-preserving system with two parameters, where two distinct arbitrary resonant modes compete. Usually, the initia...

Employing Monte Carlo sampling and a self-consistent multiscale numerical approach, we obtain a parametric simple formula for the effective electrical charge conductivity of composite systems containing randomly distributed intermetallic ne...
Problem hardness of diluted Ising models: Population annealing versus simulated annealing [0.03%]

Population annealing is a variant of the simulated annealing algorithm that improves the quality of the thermalization process in systems with rough free-energy landscapes by introducing a resampling process. We consider the diluted Sherrin...
Bistable flow dynamics of airfoil stall under varying angle of attack: A stochastic model with multiplicative noise [0.03%]

We focus on the intermittent bistable stall dynamics of an airfoil under varying angle of attack. We propose a one-dimensional Langevin equation where the stochastic forcing depends on the state of the system-high-lift attached flow or low-...
Two-stage linear filamentation growth of laser-produced proton beams in dense plasmas [0.03%]
激光等离子体中质子束的两阶段线性发丝状增长机制研究
Wang-Wen Xu,Zhang-Hu Hu,Hao-Yuan Li et al.
Wang-Wen Xu et al.
We report in this work the current filamentation instability of laser-produced proton beams in a regime where the plasma collision frequency is much smaller than the plasma oscillation frequency but larger than the growth rate of the instab...
Efficient laser-plasma acceleration of protons via near-critical mass limited targets [0.03%]

Isolated micro-targets are a promising avenue to high-performance laser-driven proton and ion accelerators due to their ability to confine the coupled laser energy to a small volume and small number of particles. Experimental results on pro...
Machine learning domain adaptation in spin models with continuous phase transitions [0.03%]
机器学习领域适应在连续相变的自旋模型中的应用

The main question raised in the article is whether a neural network trained on a spin lattice model in one universality class can be used to test a model in another universality class. The quantities of interest are the critical phase trans...
