Prethermalization

Origin of staircase prethermalization in lattice gauge theories

Quantum many-body systems with exact local gauge symmetries exhibit rich out-of-equilibrium physics such as constrained dynamics and disorder-free localization. In a joint submission, we present evidence of _staircase prethermalization_ in a $Z_2$ …

Staircase prethermalization and constrained dynamics in lattice gauge theories

The dynamics of lattice gauge theories is characterized by an abundance of local symmetry constraints. Although errors that break gauge symmetry appear naturally in NISQ-era quantum simulators, their influence on the gauge-theory dynamics is …
