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…
The distribution of the moment of inertia for harmonically trapped noninteracting Bosons at finite temperature: large deviations
Manas Kulkarni, Satya N. Majumdar, Gregory Schehr
We compute the full probability distribution of the moment of inertia of a gas of noninteracting bosons trapped in a harmonic potential $V(…
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…
Experimental evidence for strong emergent correlations between particles in a switching trap
Marco Biroli, Sergio Ciliberto, Manas Kulkarni +3
We experimentally study a system of two-dimensional Brownian particles, each confined in a harmonic trap with identical stiffness. The stiffness switches simultaneously bet…
Proxitaxis: an adaptive search strategy based on proximity and stochastic resetting
Giuseppe Del Vecchio Del Vecchio, Manas Kulkarni, Satya N. Majumdar +1
We introduce \emph{proxitaxis}, a simple search strategy where the searcher has only information about the distance from the target but not the direction. The strategy consists of…
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…
Quantum trajectories and Page-curve entanglement dynamics
Katha Ganguly, Preethi Gopalakrishnan, Atharva Naik +2
We consider time dynamics of entanglement entropy between a filled fermionic system and an empty reservoir. We consider scenarios (i) where the system is subjected to a dephasing m…
