Bose-Einstein condensates and the thin-shell limit in anisotropic bubble traps
Elias J. P. Biral, Natália S. Móller, Axel Pelster +1
Within the many different models that appeared with the use of cold atoms to design BECs the bubble trap shaped potential has been of great interest. For the anisotropic bubble tra…
Making statistics work: a quantum engine in the BEC-BCS crossover
Jennifer Koch, Keerthy Menon, Eloisa Cuestas +5
Heat engines convert thermal energy into mechanical work both in the classical and quantum regimes. However, quantum theory offers genuine nonclassical forms of energy, different f…
Emergence of damped-localized excitations of the Mott state due to disorder
R. S. Souza, Axel Pelster, F. E. A. dos Santos
A key aspect of ultracold bosonic quantum gases in deep optical lattice potential wells is the realization of the strongly interacting Mott insulating phase. Many characteristics o…
Confinement of Bose-Einstein magnon condensates in adjustable complex magnetization landscapes
Matthias R. Schweizer, Alexander J. E. Kreil, Georg von Freymann +2
Coherent wave states such as Bose-Einstein condensates (BECs), which spontaneously form in an overpopulated magnon gas even at room temperature, have considerable potential for wav…
Indication of critical scaling in time during the relaxation of an open quantum system
Ling-Na Wu, Jens Nettersheim, Julian Feß +6
Phase transitions correspond to the singular behavior of physical systems in response to continuous control parameters like temperature or external fields. Near continuous phase tr…
Controlling superfluid flows using dissipative impurities
Martin Will, Jamir Marino, Herwig Ott +1
We propose and analyze a protocol to create and control the superfluid flow in a one dimensional, weakly interacting Bose gas by noisy point contacts coupled to the density of the…
