Non-reciprocally interacting Ornstein-Uhlenbeck processes: Exceptional points, Anomalous relaxation, Pseudo-equilibrium and Boundary refrigeration
Soumya Kanti Pal, Shamik Gupta
Non-reciprocal interactions are ubiquitous in active, biological, and disordered systems, generically driving them out of equilibrium. Here, we introduce a hierarchy of non-recipro…
Resetting dynamics in a system with quenched disorder
Riya Verma, Binayak Banerjee, Shamik Gupta +1
Although resetting has widespread applicability, applying it to the dynamics in the presence of spatial quenched disorder, which is essential in many physical problems, is challeng…
Emergent Thermalization Thresholds in Unitary Dynamics of Inhomogeneously Disordered Quantum Systems
Soumya Kanti Pal, C L Sriram, Shamik Gupta
Inspired by the avalanche scenario for many-body localization (MBL) instability, we reverse the conventional set-up and ask whether a large weakly-disordered chain can thermalize a…
Canonical equilibrium of mean-field ~models in the presence of random fields
Soumya Kanti Pal, Shamik Gupta
We study canonical-equilibrium properties of Random Field Models involving classical continuous vector spins of components with mean-field interactions and subject to di…
