Fate of emergent Hilbert space fragmentation and information insulation upon softening of hard dual constraints at PXP-chain junctions
Akshay Panda, Anwesha Chattopadhyay
We demonstrate emergent Hilbert-space fragmentation in a composite chain of PXP and dual-PXP subchains separated by junctions with simultaneous blockade and anti-blockade projectio…

Rectification from band gap oscillation
Anwesha Chattopadhyay
We study a one-dimensional chain of identical atoms with two electronic orbitals and two electrons per atom, subject to an external oscillating pressure that periodically modulates…

Oscillatory and dissipative dynamics of complex probability in non-equilibrium stochastic processes
Anwesha Chattopadhyay
For a Markov and stationary stochastic process described by the well-known classical master equation, we introduce complex transition rates instead of real transition rates to stud…
