We investigate a variant of the two-state q-voter model in which agents update their states under a random external field (which points upward with probability s and downward with probability 1-s) with probability p or adopt the unanimous o...
Stability of universal properties against perturbations of the Markov chain Monte Carlo algorithm [0.03%]

We numerically investigate the stability of universal properties at continuous phase transitions against perturbations of the Markov chain Monte Carlo algorithm used to simulate the system. We consider the three-dimensional XY model as a te...
Symmetry breaking in chaotic many-body quantum systems at finite temperature [0.03%]
有限温度下混沌量子多体系统中的对称性破缺

Recent work has shown that the entanglement of finite-temperature eigenstates in chaotic quantum many-body local Hamiltonians can be accurately described by an ensemble of random states with an internal U(1) symmetry. We build upon this res...

Embryonic development relies on the formation of sharp, precise gene expression boundaries. In the fruit fly Drosophila melanogaster, boundary formation has been proposed to occur at a dynamical critical point. Yet, in the paradigmatic case...
Existence diagrams and excitations of vector Akhmediev breathers with self-steepening [0.03%]
自陡峭效应下的矢量Akhmediev呼吸态存在图与激发态

We revisit vector breathers with self-steepening in both focusing and defocusing regimes. We present previously unknown existence diagrams of Akhmediev breathers in a frequency-wave-number plane, which can be used to identify a family of no...
Three-dimensional phase-field simulations of water freezing and thawing at pore scale [0.03%]

This work deals with numerical simulation of water freezing and thawing in a complex three-dimensional geometry of a porous medium. The porous structure is represented by a virtual container filled with glass beads. Phase transition modelin...
Spreading processes on heterogeneous active systems: Spreading threshold, immunization strategies, and vaccination noise [0.03%]
异质活性系统中的传播过程：传播阈值、免疫策略和疫苗接种噪声

We study spreading processes in two-dimensional systems of heterogeneous active agents that exhibit different individual active speeds. We obtain, combining kinetic and complex network theory, an analytical expression for the spreading thre...

This work introduces a generic quantitative framework for studying dynamical processes that involve interactions of polymer sequences. Possible applications range from quantitative studies of the reaction kinetics of polymerization processe...

The study of the Ising model from a percolation perspective has played a significant role in the modern theory of critical phenomena. We consider the celebrated square-lattice Ising model and construct percolation clusters by placing bonds,...

In this work, an improved discrete unified gas kinetic scheme (DUGKS) is proposed. Like the original DUGKS and the optimized DUGKS, the improved DUGKS uses trapezoidal rule for the integration of the collision term, and introduces two auxil...
