Emergent criticality in a constrained boson model
Anirudha Menon, Anwesha Chattopadhyay, K. Sengupta +1
We show, via explicit computation on a constrained bosonic model, that the presence of subsystem symmetries can lead to a quantum phase transition (QPT) where the critical point ex…

Emergence of a quasi-ergodic steady state in a dissipative Tavis-Cummings array
Debabrata Mondal, K. Sengupta, Subhasis Sinha
In an atom-photon interacting system described by Tavis Cummings Hubbard (TCH) model, we demonstrate the emergence of a quasi-steady state in a dissipative environment that exhibit…
