The quantum harmonic oscillator in a dissipative bath of anyon pairs
Nils-Henrik Meyer, Axel Pelster, Michael Thorwart
We generalize the formalism of open quantum systems to introduce anyon baths. In particular, we work out a dissipative anyon bath composed of independent pairs of one-dimensional G…
Cavity-induced quantum droplets
Leon Mixa, Milan RadonjiÄ, 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 RadonjiÄ, 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…
Generalized Josephson effect with arbitrary periodicity in quantum magnets
Anshuman Tripathi, Felix Gerken, Peter Schmitteckert +3
Easy-plane quantum magnets are strikingly similar to superconductors, allowing for spin supercurrent and an effective superconducting phase stemming from their rotation symm…
