Non-monotonic diffusion from nonequilibrium driving
Manish Patel, Ritwick Sarkar, Urna Basu +1
The stochastic dynamics of interacting particles far from equilibrium remains a fundamental challenge in statistical physics. While reciprocal interactions often permit effective o…
Stochastic Two-temperature Nonequilibrium Ising model
Debraj Dutta, Ritwick Sarkar, Urna Basu
We investigate the nonequilibrium stationary state (NESS) of the two-dimensional Ising model under a stochastic dichotomous modulation of temperature, which alternates between $T_c…
From Attraction to Repulsion: Emergent Interactions in Harmonically Coupled Active Binary System
Ritwick Sarkar, Sreya Chatterjee, Urna Basu
We investigate the emergent interactions between two active Brownian particles coupled by an attractive harmonic potential and in contact with a thermal reservoir. By analyzing the…
Tracer dynamics in an interacting active bath: fluctuations and energy partition
Ritwick Sarkar, Ion Santra
We investigate the dynamics of a massive tracer particle coupled to an interacting active bath, modeled as a harmonic chain of overdamped active particles analytically, with an aim…
Emergent short-range repulsion for attractively coupled active particles
Ritwick Sarkar, Urna Basu
We show that heterogeneity in self-propulsion speed can lead to the emergence of a robust effective short-range repulsion among active particles interacting via long-range attracti…
Harmonic chain driven by active Rubin bath: transport properties and steady-state correlations
Ritwick Sarkar, Ion Santra, Urna Basu
Characterizing the properties of an extended system driven by active reservoirs is a question of increasing importance. Here we address this question in two steps. We start by inve…
Stationary state of harmonic chains driven by boundary resetting
Ritwick Sarkar, Pritam Roy
We study the nonequilibrium steady state (NESS) of an ordered harmonic chain of oscillators connected to two walls which undergo diffusive motion with stochastic resetting. The…
Stationary states of activity-driven harmonic chains
Ritwick Sarkar, Ion Santra, Urna Basu
We study the stationary state of a chain of harmonic oscillators driven by two active reservoirs at the two ends. These reservoirs exert correlated stochastic forces on the boundar…
Strain localization and yielding dynamics in disordered collagen networks
Swarnadeep Bakshi, Vaisakh VM, Ritwick Sarkar +1
Collagen is the most abundant extracellular-matrix protein in mammals and the main structural and load-bearing element of connective tissues. Collagen networks show remarkable stra…
