Fixed Points and Universality Classes in Coupled Kardar-Parisi-Zhang Equations
Dipankar Roy, Abhishek Dhar, Manas Kulkarni +1
We study coupled KPZ equations with three control parameters . These equations are used in the context of stretched polymers in a random medium, for the spacetime spin-spin…
Page curve like dynamics in Interacting Quantum Systems
Tamoghna Ray, Abhishek Dhar, Manas Kulkarni
We study the dynamics of entanglement in a one-dimensional spin- chain, with and without integrability-breaking interactions, that is connected to a bath. We start from…
Spikes in Poissonian quantum trajectories
Alan Sherry, Cedric Bernardin, Abhishek Dhar +2
We consider the dynamics of a continuously monitored qubit in the limit of strong measurement rate where the quantum trajectory is described by a stochastic master equation with Po…
Harmonically confined particles with long-range repulsive interactions
Sanaa Agarwal, Abhishek Dhar, Manas Kulkarni +4
We study an interacting system of classical particles on a line at thermal equilibrium. The particles are confined by a harmonic trap and repelling each other via pairwise inte…
