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 (…

Measuring the single-particle density matrix for fermions and hard-core bosons in an optical lattice
Luis A. Peña Ardila, Markus Heyl, André Eckardt
Ultracold atoms in optical lattices provide clean, tunable, and well-isolated realizations of paradigmatic quantum lattice models. With the recent advent of quantum-gas microscopes…
