Engineering many-body quantum Hamiltonians with non-ergodic properties using quantum Monte Carlo
Nyayabanta Swain, Ho-Kin Tang, Darryl Chuan Wei Foo +5
We present a computational framework to identify Hamiltonians of interacting quantum many-body systems that host non-ergodic excited states. We combine quantum Monte Carlo simulati…
