Impurities and polarons in bosonic quantum gases: a review on recent progress
F. Grusdt, N. Mostaan, E. Demler +1
This review describes the field of Bose polarons, arising when mobile impurities are immersed into a bosonic quantum gas. The latter can be realized by a Bose-Einstein condensate (…

Spectroscopy of Hubbard-Mott excitons and their ro-vibrational excitations
Annabelle Bohrdt, Eugene Demler, Fabian Grusdt
Hubbard excitons are bound states of doublons and holes that can be experimentally probed both in real materials, such as cuprates, and in cold atom quantum simulators. Here we com…
