Dressed Floquet scars from protected zero modes in a Rydberg chain
Saptadip Roy, Bhaskar Mukherjee, K. Sengupta +1
In this Letter, we present an approximate analytic construction of two zero quasienergy quantum many-body scars in a periodically driven model of Rydberg atoms on a ring, which per…
Emergent prethermal Bethe integrability in a periodically driven Rydberg chain
Saptadip Roy, Arnab Sen, Diptiman Sen +1
We study a chain of periodically driven Rydberg atoms and identify a class of drive protocols for which the system exhibits emergent prethermal Bethe integrability at special drive…
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…
Scar-induced imbalance in staggered Rydberg ladders
Mainak Pal, Madhumita Sarkar, K. Sengupta +1
We demonstrate that the kinematically-constrained model of Rydberg atoms on a two-leg ladder with staggered detuning, , has quantum many-body scars (QMBS) in its spect…
