Quantum Many-body Scars in Z2 Lattice Gauge Theory
ORAL
Abstract
Quantum many-body scars are eigenstates in non-integrable isolated quantum systems that defy typical thermalization paradigms, violating the eigenstate thermalization hypothesis and quantum ergodicity. We identify exact analytic scar solutions in a quasi-1d limit of a 2 + 1 dimensional lattice gauge theory. We propose an experimental protocol for the scars preparation using mid-circuit measurements, offering a benchmark for quantum simulation experiments addressing strong-coupling non-equilibrium phenomena beyond classical simulation capabilities.
