Non-Equilibrium Phase Transition in a Boundary-Driven Dissipative Fermionic Chain
Hao Chen, Wucheng Zhang, Manas Kulkarni +1
We demonstrate that a boundary-localized periodic (Floquet) drive can induce nontrivial long-range correlations in a non-interacting fermionic chain which is additionally subject t…
Dynamics of number entropy for free fermionic systems in presence of defects and stochastic processes
Atharva Naik, Bijay Kumar Agarwalla, Manas Kulkarni
We investigate the dynamics of number entropy in a chain of free fermions subjected to both defects and stochastic processes. For a special class of defects, namely conformal defec…
Quantum dynamics in lattices in presence of bulk dephasing and a localized source
Tamoghna Ray, Katha Ganguly, Dario Poletti +2
The aim of this work is to study the dynamics of quantum systems subjected to a localized fermionic source in the presence of bulk dephasing. We consider two classes of one-dimensi…
Dynamically generated correlations in a trapped bosonic gas via frequency quenches
Nikhil Mesquita, Manas Kulkarni, Satya N. Majumdar +1
We study a system of noninteracting bosons in a harmonic trap subjected to repeated quantum quenches, where the trap frequency is switched from one value to another after a ran…
Assessment of spectral phases of non-Hermitian quantum systems through complex and singular values
Mahaveer Prasad, S. Harshini Tekur, Bijay Kumar Agarwalla +1
Chaotic behavior or lack thereof in non-Hermitian systems is often diagnosed via spectral analysis of associated complex eigenvalues. Very recently, singular values of the associat…
Emergence of coupled Korteweg-de Vries equations in fields
Sharath Jose, Manas Kulkarni, Vishal Vasan
The Korteweg-de Vries (KdV) equation is of fundamental importance in a wide range of subjects with generalization to multi-component systems relevant for multi-species fluids and c…
