Non-monotonic diffusion from nonequilibrium driving
Manish Patel, Ritwick Sarkar, Urna Basu +1
The paper presents a unified theoretical framework for particles with reciprocal and nonreciprocal couplings and studies the diffusion of a passive particle driven by an active par…
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…
