Quantum Dynamics of Full Counting Statistics in Fermionic Lattices with Localized Gain
Bijay Kumar Agarwalla, Manas Kulkarni
We investigate the dynamics of full counting statistics (FCS) of the growth of the total number of fermions in a one-dimensional non-interacting lattice subjected to a localized pa…
Symmetry structure dependent diagnostic of the Quantum Mpemba Effect
Tamizhselvan S, Manju C, Bijay Kumar Agarwalla +1
Understanding symmetry restoration in isolated quantum many-body systems is an important problem in nonequilibrium many-body quantum physics. Recent studies have shown that the qua…
Long-time Dynamics of Many-body Open Quantum Systems using Quantum Generating Functions
Katha Ganguly, Dario Poletti, Bijay Kumar Agarwalla
The interplay between coherent unitary evolution and environment-induced dissipation can give rise to a wide range of non-equilibrium dynamics in open quantum systems, ranging from…
Quantum Mpemba effect for operators in open systems
Pitambar Bagui, Bijay Kumar Agarwalla
The quantum Mpemba effect concerns with anomalous relaxation of quantum states that evolves either under unitary or non-unitary dynamics. In the context of open quantum systems, wh…
Principal component analysis of wavefunction snapshots in non-equilibrium dynamics
Dharmesh Yadav, Devendra Singh Bhakuni, Bijay Kumar Agarwalla
We study non-equilibrium quantum dynamics by performing principal component analysis on the data sets of wavefunction snapshots. We show that a specific transformation of the data…
Measurement induced faster symmetry restoration in quantum trajectories
Katha Ganguly, Bijay Kumar Agarwalla
Continuous measurement of quantum systems provides a standard route to quantum trajectories through the successive acquisition of information which further results in measurement b…
