Long-lived oscillations of metastable states in neutral atom systems
Siva Darbha, Milan KornjaÄa, Fangli Liu +7
Metastable states arise in a range of quantum systems and can be observed in various dynamical scenarios, including decay, bubble nucleation, and long-lived oscillations. The pheno…

False vacuum decay and nucleation dynamics in neutral atom systems
Siva Darbha, Milan KornjaÄa, Fangli Liu +7
Metastable states of quantum many-body systems with confinement offer a means to simulate false vacuum phenomenology, including non-equilibrium dynamical processes like decay by nu…
