Nonadiabatic energy fluctuations of scale-invariant quantum systems in a time-dependent trap
Mathieu Beau, Adolfo del Campo
We consider the nonadiabatic energy fluctuations of a many-body system in a time-dependent harmonic trap. In the presence of scale-invariance, the dynamics becomes self-similar and…

Nonexponential quantum decay under environmental decoherence
M. Beau, J. Kiukas, I. L. Egusquiza +1
An unstable quantum state generally decays following an exponential law, as environmental decoherence is expected to prevent the decay products from recombining to reconstruct the…
