Selective decoupling in multi-level quantum systems by the SU(2) sign anomaly
Giorgio Anfuso, Giulia Piccitto, Vittorio Romano +2
We investigate dynamical decoupling operated by -pulses in a two-level subspaces of a multilevel system showing that it may leads to selective decoupling. This provides a flexi…

Dissipation and non-thermal states in cryogenic cavities
Zeno Bacciconi, Giulia Piccitto, Alessandro Maria Verga +3
We study the properties of photons in a cryogenic cavity, made by cryo-cooled mirrors surrounded by a room temperature environment. We model such a system as a multimode cavity cou…
