Quasiparticle tunneling in a periodically driven bosonic Josephson junction
Bettina Gertjerenken, Martin Holthaus
A resonantly driven bosonic Josephson junction supports stable collective excitations, or quasiparticles, which constitute analogs of the Trojan wave packets previously explored wi…
Fluctuations of the order parameter of a mesoscopic Floquet condensate
Bettina Gertjerenken, Martin Holthaus
We suggest that nonequilibrium Bose-Einstein condensates may occur in time-periodically driven interacting Bose gases. Employing the model of a periodically forced bosonic Josephso…
Trojan quasiparticles
Bettina Gertjerenken, Martin Holthaus
We argue that a time-periodically driven bosonic Josephson junction supports stable, quasi-particle-like collective response modes which are -particle analogs of the nonspreadin…
Reproducible mesoscopic superpositions of Bose-Einstein condensates and mean-field chaos
Bettina Gertjerenken, Stephan Arlinghaus, Niklas Teichmann +1
In a parameter regime for which the mean-field (Gross-Pitaevskii) dynamics becomes chaotic, mesoscopic quantum superpositions in phase space can occur in a double-well potential wh…
