Mean-field approach to Rydberg facilitation in a gas of atoms at high and low temperatures
Daniel Brady, Michael Fleischhauer
The excitation spread caused by Rydberg facilitation in a gas of laser driven atoms is an interesting model system for studying epidemic dynamics. We derive a mean-field approach t…
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…
Strong-coupling Bose polarons in 1D: Condensate deformation and modified Bogoliubov phonons
Jonas Jager, Ryan Barnett, Martin Will +1
We discuss the interaction of a quantum impurity with a one-dimensional degenerate Bose gas forming a Bose-polaron. In three spatial dimensions the quasiparticle is typically well…
Synthetic magnetic fields for cold erbium atoms
Daniel Babik, Roberto Röll, David Helten +2
The implementation of the fractional quantum Hall effect in ultracold atomic quantum gases remains, despite substantial advances in the field, a major challenge. Since atoms are el…
Dynamical variational approach to Bose polarons at finite temperatures
David Dzsotjan, Richard Schmidt, Michael Fleischhauer
We discuss the interaction of a mobile quantum impurity with a Bose-Einstein condensate of atoms at finite temperature. To describe the resulting Bose polaron formation we extend t…
The one-dimensional Bose-Fermi-Hubbard model in the limit of fast fermions
Alexander Mering, Michael Fleischhauer
We discuss the ground-state phase diagram of the one-dimensional Bose-Fermi-Hubbard model (BFHM) in the limit of fast fermions based on an effective boson model. We give a detailed…
