Universal Properties of Anisotropic Dipolar Bosons in Two Dimensions
J. Sánchez-Baena, L. A. Peña Ardila, G. Astrakharchik +1
The energy of ultra-dilute quantum many-body systems is known to exhibit a universal dependence on the gas parameter , with the density, the dimensionality of th…
The origin of the period- quasi-breathing in disk-shaped Gross-Pitaevskii breathers
J. Torrents, V. Dunjko, M. Gonchenko +2
We address the origins of the quasi-periodic breathing observed in [Phys. Rev.\ X vol. 9, 021035 (2019)] in disk-shaped harmonically trapped two-dimensional Bose condensates, where…
Hole-induced anomaly in the thermodynamic behavior of a one-dimensional Bose gas
Giulia De Rosi, Riccardo Rota, Grigori E. Astrakharchik +1
We reveal an intriguing anomaly in the temperature dependence of the specific heat of a one-dimensional Bose gas. The observed peak holds for arbitrary interaction and remembers a…
Polaron Interactions and Bipolarons in One-Dimensional Bose Gases in the Strong Coupling Regime
Martin Will, Gregory E. Astrakharchik, Michael Fleischhauer
Bose polarons, quasi-particles composed of mobile impurities surrounded by cold Bose gas, can experience strong interactions mediated by the many-body environment and form bipolaro…
