Cavity-induced quantum droplets
Leon Mixa, Milan Radonjić, Axel Pelster +1
Quantum droplets are formed in quantum many-body systems when the competition of quantum corrections with the mean-field interaction yields a stable self-bound quantum liquid. We p…
Engineering quantum droplet formation by cavity-induced long-range interactions
Leon Mixa, Milan Radonjić, Axel Pelster +1
We investigate a dilute Bose gas with both a short-range contact and an effective long-range interaction between the atoms. The latter is induced by the strong coupling to a cavity…
Observation of Shapiro steps in an ultracold atomic Josephson junction
Erik Bernhart, Marvin Röhrle, Vijay Pal Singh +3
The current-voltage characteristic of a driven superconducting Josephson junction displays discrete steps. This phenomenon, called the Shapiro steps, forms today's voltage standard…
Impurities in a trapped 1D Bose gas of arbitrary interaction strength: localization-delocalization transition and absence of self-localization
Dennis Breu, Eric Vidal Marcos, Martin Will +1
We discuss impurities in a one-dimensional Bose gas with arbitrary boson-boson and boson-impurity interactions. To fully account for quantum effects, we employ numerical simulation…
Spin self-organization in an optical cavity facilitated by inhomogeneous broadening
Marc Nairn, Luigi Giannelli, Giovanna Morigi +3
We study the onset of collective spin-self-organization in a thermal ensemble of driven two-level atoms confined in an optical cavity. The atoms spontaneously form a spin-pattern a…
Nanomechanically-induced nonequilibrium quantum phase transition to a self-organized density wave of a Bose-Einstein condensate
Milan Radonjić, Leon Mixa, Axel Pelster +1
We report on a nonequilibrium quantum phase transition (NQPT) in a hybrid quantum many-body system consisting of a vibrational mode of a damped nanomembrane interacting optomechani…
