Universal dynamics from a single-particle dark state
Ruben Daraban, Arghavan Safavi-Naini, Johannes Schachenmayer +1
Open quantum systems can host dark or subradiant states whose decay is highly suppressed. While these states have been extensively studied in the few-excitation regime, their impac…

Permutation-invariant codes: a numerical study and qudit constructions
Liam J. Bond, Jiří Minář, Māris Ozols +2
We investigate Permutation-Invariant (PI) quantum error-correcting codes encoding a logical qudit of dimension in PI states using physical qudits of dimensi…

Nonequilibrium quantum thermodynamics of determinantal many-body systems: Application to the Tonks-Girardeau and ideal Fermi gases
Y. Y. Atas, A. Safavi-Naini, K. V. Kheruntsyan
We develop a general approach for calculating the characteristic function of the work distribution of quantum many-body systems in a time-varying potential, whose many-body wave fu…
