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 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…
