Constraint-induced breaking and restoration of ergodicity in spin-1 PXP models
Bhaskar Mukherjee, Zi Cai, W. Vincent Liu
Eigenstate Thermalization Hypothesis(ETH) has played a pivotal role in understanding ergodicity and its breaking in isolated quantum many-body systems. Recent experiment on 51-atom…

Collapse and revival of quantum many-body scars via Floquet engineering
Bhaskar Mukherjee, Sourav Nandy, Arnab Sen +2
The presence of quantum scars, athermal eigenstates of a many-body Hamiltonian with finite energy density, leads to absence of ergodicity and long-time coherent dynamics in closed…
