We consider a particle undergoing run and tumble dynamics, in which its velocity
stochastically reverses, in one dimension. We study the addition of a Poissonian resetting …

Exact solutions of interacting random walk models, such as 1D lattice gases, offer precise
insight into the origin of nonequilibrium phenomena. Here, we study a model of run-and …

Fluctuations in stochastic systems are usually characterized by full counting statistics, which
analyzes the distribution of the number of events taking place in the fixed time interval. In an …

The existence of a corrugated surface is of great importance and ubiquity in biological
systems, exhibiting diverse dynamic behaviors. However, it has remained unclear whether …

Bacteria such as Escherichia coli move about in a series of runs and tumbles: while a run
state (straight motion) entails all the flagellar motors spinning in counterclockwise (CCW) …

本文研究了周期对称势中时间非对称外力驱动的布朗粒子输运现象, 建立了分数阶布朗马达输运
模型. 其中外力是零均值的, 而分数阶阶数则刻画了客观环境的非均匀性程度 …

在对分数阶布朗马达输运现象研究的基础上, 引入了描述系统势场对称性的参数(简称对称性
参数), 并详细分析了该参数及记忆性参数(分数阶阶数) 对粒子输运状态的影响. 仿真结果表明 …

Nonequilibrium statistical mechanics deals with noisy systems whose dynamics breaks time-
reversal symmetry. Stochastic Markov processes form a mathematical framework for a …

We aim to explore the validity of recently proposed 'thermodynamic uncertainty
relations'(universal entropic bounds on current fluctuations) in non-Markovian systems. First …

Dynein and kinesin are two such proteins that perform directed motion on cytoskeletal
filaments (microtubules), in opposite directions. They move typically with speed of hundreds …
