Probing Bardeen-Cooper-Schrieffer pairing and quasiparticle formation in ultracold gases by Rydberg atom spectroscopy
Emilio Ramos RodrÃguez, Marcel Gievers, Richard Schmidt
Locally probing pairing in fermionic superfluids, ranging from micro- to macroscopic scales, has been a long-standing challenge. Here, we investigate a new approach that uses Rydbe…

Polarons in atomic gases and two-dimensional semiconductors
Pietro Massignan, Richard Schmidt, Grigori E. Astrakharchik +4
In this work we provide a comprehensive review of theoretical and experimental studies of the properties of polarons formed by mobile impurities strongly interacting with quantum m…
