Tracer diffusion in crowded narrow channels

O Bénichou, P Illien, G Oshanin… - Journal of Physics …, 2018 - iopscience.iop.org
We summarise different results on the diffusion of a tracer particle in lattice gases of hard-
core particles with stochastic dynamics, which are confined to narrow channels—single-files …

Eigenvalue crossing as a phase transition in relaxation dynamics

G Teza, R Yaacoby, O Raz - Physical review letters, 2023 - APS
When a system's parameter is abruptly changed, a relaxation toward the new equilibrium of
the system follows. We show that a crossing between the second and third eigenvalues of …

Macroscopic fluctuation theory and current fluctuations in active lattice gases

T Agranov, S Ro, Y Kafri, V Lecomte - SciPost Physics, 2023 - scipost.org
We study the current large deviations for a lattice model of interacting active particles
displaying a motility-induced phase separation (MIPS). To do this, we first derive the exact …

Large deviations in statistics of the local time and occupation time for a run and tumble particle

S Mukherjee, P Le Doussal, NR Smith - Physical Review E, 2024 - APS
We investigate the statistics of the local time T=∫ 0 T δ (x (t)) dt that a run and tumble
particle (RTP) x (t) in one dimension spends at the origin, with or without an external drift. By …

Entropy production and its large deviations in an active lattice gas

T Agranov, ME Cates, RL Jack - Journal of Statistical Mechanics …, 2022 - iopscience.iop.org
Active systems are characterized by a continuous production of entropy at steady state. We
study the statistics of entropy production within a lattice-based model of interacting active …

Tricritical behavior in dynamical phase transitions

T Agranov, ME Cates, RL Jack - Physical Review Letters, 2023 - APS
We identify a new scenario for dynamical phase transitions associated with time-integrated
observables occurring in diffusive systems described by the macroscopic fluctuation theory …

Full statistics of nonstationary heat transfer in the Kipnis–Marchioro–Presutti model

E Bettelheim, NR Smith, B Meerson - Journal of Statistical …, 2022 - iopscience.iop.org
We investigate non-stationary heat transfer in the Kipnis–Marchioro–Presutti (KMP) lattice
gas model at long times in one dimension when starting from a localized heat distribution. At …

Dynamical phase transition in the occupation fraction statistics for noncrossing Brownian particles

S Mukherjee, NR Smith - Physical Review E, 2023 - APS
We consider a system of N noncrossing Brownian particles in one dimension. We find the
exact rate function that describes the long-time large deviation statistics of their occupation …

Large deviations in chaotic systems: Exact results and dynamical phase transition

NR Smith - Physical Review E, 2022 - APS
Large deviations in chaotic dynamics have potentially significant and dramatic
consequences. We study large deviations of series of finite lengths N generated by chaotic …

Universal anomalous fluctuations in charged single-file systems

Ž Krajnik, J Schmidt, V Pasquier, T Prosen… - Physical Review …, 2024 - APS
Introducing a general class of one-dimensional single-file systems (meaning that particle
crossings are prohibited) of interacting hardcore particles with internal degrees of freedom …
