Approach to Steady-State in Nested Resetting Processes
Callum Britton, Ben Le Jeune, Henry Alston +2
We characterise the approach to nonequilibrium steady state in nested resetting processes by deriving accumulation times for the system, which quantify the effective first-passage…
Persistence, resetting, and first-passage times of an active Ornstein--Uhlenbeck particle
Demosthenes K. Georgiou, Paul C. Bressloff, Thibault Bertrand
We study the first-passage time statistics of an active Ornstein--Uhlenbeck particle on a finite one-dimensional interval with an absorbing boundary at one end and a reflecting bou…
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…
Finite-Time Optimal Control by Noisy Traps
Luca Cocconi, Henry Alston, Thibault Bertrand
The optimal control of passive systems in equilibrium typically favours quasistatic (infinite-time) protocols. We show that a breakdown of quasistatic optimality occurs when the co…
Controlling the Glass Transition through Active Fluctuating Interactions
Emir Sezik, Henry Alston, Thibault Bertrand
Fluctuating pairwise interactions are understood to drive fluid-like states in dense biological systems. These states find a broad range of functionalities, such as directing growt…
Stochastic Forces Enhance Tracer Diffusion in Non-motile Active Matter
Henry Alston, Raphael Voituriez, Thibault Bertrand
Stochasticity is a defining feature of the pairwise forces governing interactions in biological systems-from molecular motors to cell-cell adhesion-yet its consequences on large-sc…
Conditional splitting probabilities for hidden-state inference in drift-diffusive processes
Emir Sezik, Jacob Knight, Henry Alston +4
Splitting probabilities quantify the likelihood of particular outcomes out of a set of mutually-exclusive possibilities for stochastic processes and play a central role in first-pa…
Nested Stochastic Resetting: Nonequilibrium Steady-states and Exact Correlations
Henry Alston, Callum Britton, Thibault Bertrand
Stochastic resetting breaks detailed balance and drives the formation of nonequilibrium steady states . Here, we consider a chain of diffusive processes that interact unil…
The OU process: Characterising dissipative confinement in noisy traps
Luca Cocconi, Henry Alston, Jacopo Romano +1
The Ornstein-Uhlenbeck (OU) process describes the dynamics of Brownian particles in a confining harmonic potential, thereby constituting the paradigmatic model of overdamped, mean-…
Boosting macroscopic diffusion with local resetting
Henry Alston, Thibault Bertrand
Stochastic interactions generically enhance self-diffusivity in living and biological systems, e.g. optimizing navigation strategies and controlling material properties of cellular…
Active Jamming at Criticality
Shalabh K. Anand, Chiu Fan Lee, Thibault Bertrand
Jamming is ubiquitous in disordered systems, but the critical behavior of jammed solids subjected to active forces or thermal fluctuations remains elusive. In particular, while pas…
