Non-Hermitian Topological End-Mode Lasing in Polariton Systems
Paolo Comaron, Vanik Shahnazaryan, Wojciech Brzezicki +2
We predict the existence of non-Hermitian topologically protected end states in a one-dimensional exciton-polariton condensate lattice, where topological transitions are driven by…

Persistent current formation in double-ring geometries
Thomas Bland, Quentin Marolleau, Paolo Comaron +2
Quenching an ultracold bosonic gas in a ring across the Bose-Einstein condensation phase transition is known, and has been experimentally observed, to lead to the spontaneous emerg…

Quench dynamics of an ultracold two-dimensional Bose gas
Paolo Comaron, Fabrizio Larcher, Franco Dalfovo +1
We study the dynamics of a two-dimensional Bose gas after an instantaneous quench of an initially ultracold thermal atomic gas across the Berezinskii-Kosterlitz-Thouless phase tran…
