This work extends the universal finite-size scaling framework for continuum percolation from two-dimensional (2D) to quasi-three-dimensional (Q3D) stick systems, in which sequentially deposited wires of finite diameter stack vertically on a...
Generalized Jarzynski inequalities for dissipative and field-theoretic systems [0.03%]
耗散和场论系统的广义Jarzynski不等式

The Jarzynski equality, which relates equilibrium free-energy difference to an average of nonequilibrium work, plays a central role in modern nonequilibrium statistical thermodynamics. In this paper we study a weaker consequence of this rel...
Stability and interactions of hopfions in confined chiral systems: Role of the background phase [0.03%]

We present a systematic study of isolated hopfions in confined layers of chiral magnets and cholesteric liquid crystals with strong surface anchoring and a film thickness fixed to one spiral pitch. We focus on the structure, stability, and ...
Fluctuation-response relation for a nonequilibrium system with resolved Markovian embedding [0.03%]
具有可解马尔科夫嵌入的非平衡系统中的涨落-响应关系

Rémi Goerlich et al.
Fluctuation-response relations must be modified to describe nonequilibrium systems with non-Markovian dynamics. Here, we experimentally demonstrate that such relation is quantitatively recovered when the appropriate Markovian embedding of t...

In liquid mixtures, changes in structural decay have been observed in particle simulations and experiments, and are an important element of their analysis. The work presents a comprehensive description of the long-range behavior of structur...
Exact stationary state of a d-dimensional run-and-tumble particle in a harmonic potential [0.03%]
各向同性张量流体中缺陷的动力学标度和剪切模化现象中的普适临界指数

We derive the exact nonequilibrium steady state of a run-and-tumble particle (RTP) in d dimensions confined in an isotropic harmonic trap V(r)=μr^{2}/2, with r=∥r∥. Rotational invariance reduces the problem to the stationary single-coord...
Inefficiency of the block approximation in diploid probabilistic cellular automata [0.03%]
二倍体概率细胞自动机中块近似法的低效性

Emilio N M Cirillo et al.
We study a probabilistic cellular automaton obtained as a mixture of the additive elementary rules 60 and 102. We prove that for any finite periodic lattice and for mixing parameter λ=1/2, the system almost surely reaches the absorbing all...
Tokamak level performance in the optimized stellarator Wendelstein 7-X with stable peaked density profiles [0.03%]
具有稳定的密度峰值分布的优化级 stellarator Wendelstein 7-X 中的托卡马克性能水平

S Bannmann et al.
Progress towards achieving net gain from nuclear fusion is typically characterized by the triple product nTτ. Although stellarators have several benefits for a reactor, such as the inherent steady-state capability and the lack of disruptio...
Memory-driven anomalous transport and reactions in comblike media: A unified framework for non-Markovian convection, subdiffusion, and ergodicity breaking [0.03%]
记忆驱动的奇异传输和组合介质中的反应：非马尔可夫对流、次扩散和非遍历性的统一框架
Guitian He,Zichao Yang,Maokang Luo et al.
Guitian He et al.
We introduce a generalized comb geometry based on a continuous-time random walk that unifies longitudinal advection, transverse trapping, and reversible reactions with temporal memory. By deriving macroscopic evolution equations from this m...
High-precision simulations of the parity-conserving directed-percolation universality class in 1+1 dimensions [0.03%]

Next to the directed-percolation (DP) universality class, parity-conserving directed-percolation (pcDP; also called parity-conserving branching-annihilating random walks) is the second-most important model with an absorbing state transition...
