Relaxation dynamics in a long-range system with mixed Hamiltonian and non-Hamiltonian interactions
Alessandro Campa, Shamik Gupta
Sometimes the dynamics of a physical system is described by non-Hamiltonian equations of motion, and additionally, the system is characterized by long-range interactions. A concret…
Martingales for physicists: A treatise on stochastic thermodynamics and beyond
Édgar Roldán, Izaak Neri, Raphael Chetrite +4
We review the theory of martingales as applied to stochastic thermodynamics and stochastic processes in physics more generally.
Stochastic resets in the context of a tight-binding chain driven by an oscillating field
Sushanta Dattagupta, Debraj Das, Shamik Gupta
In this work, we study in the framework of the so-called driven tight-binding chain (TBC) the issue of quantum unitary dynamics interspersed at random times with stochastic resets…
Biased random walk on random networks in presence of stochastic resetting: Exact results
Mrinal Sarkar, Shamik Gupta
We consider biased random walks on random networks constituted by a random comb comprising a backbone with quenched-disordered random-length branches. The backbone and the branches…
Self-similar inhomogeneous stationary states under constrained dynamics
Soumen Das, Shankar Ghosh, Shamik Gupta
The dynamics of rigid objects, each having degrees of freedom, is played out in the configuration space of dimension . Being rigid, there are additional constraints at…
Synchronization in the Kuramoto model in presence of stochastic resetting
Mrinal Sarkar, Shamik Gupta
What happens when the paradigmatic Kuramoto model involving interacting oscillators of distributed natural frequencies and showing spontaneous collective synchronization in the sta…
