Non-Abelian Spin Counting of Ordered Stochastic Trajectories: Reentrant Finite-Time Chern Numbers
Yangyang Du
Conventional full counting statistics assigns commuting phases to integrated stochastic currents and therefore resolves net transport but not, in general, the temporal ordering of…
Run-and-tumble particles with preferred reorientation
Callum Britton, Ziluo Zhang, Seongjun Han +1
Run-and-tumble particles (RTPs) are canonically modeled with uniform reorientation probabilities, an assumption that breaks down for many biological microswimmers. In this work, we…
Cramer-Rao Inequality Generalizes the Equilibrium Energy Fluctuation-Response Relation to Nonequilibrium Steady States
Shaofan Liu, Raphael Chetrite, Andre C. Barato
Equilibrium steady states are fully characterized by the Boltzmann distribution, which depends only on the energy and the temperature. In contrast, nonequilibrium steady states, wh…
Free-Energy Differences from Nonequilibrium Fluctuations in High Dissipation
Sreekanth K Manikandan, Giovanni Volpe
Equilibrium free-energy differences can be measured from nonequilibrium work fluctuations using fluctuation theorems, such as the Jarzynski equality and the Crooks fluctuation theo…
Universality of superdiffusion in simple random graphs
Mrinal Sarkar, Nicolò Defenu, Tilman Enss
Random walks with long-range jumps can drive superdiffusive transport, replacing ordinary diffusion with an effective long-range kinetic operator. Such superdiffusive kinetics is a…
Coarse-grained kinetic scale tightens thermodynamic spectral bounds of Markov cycles
Rongxing Xu, Cuiling Meng
Thermodynamic bounds on the spectrum of a Markov cycle depend on the cycle affinity and maximum escape rate, but they ignore how the local transition rates are distributed around t…
