Probing Bardeen-Cooper-Schrieffer pairing and quasiparticle formation in ultracold gases by Rydberg atom spectroscopy
Emilio Ramos Rodríguez, 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…
Probing polaron clouds by Rydberg atom spectroscopy
Marcel Gievers, Marcel Wagner, Richard Schmidt
In recent years, Rydberg excitations in atomic quantum gases have become a successful platform to explore quantum impurity problems. A single impurity immersed in a Fermi gas leads…
Shape effects of localized losses in quantum wires: dissipative resonances and nonequilibrium universality
Thomas Müller, Marcel Gievers, Heinrich Fröml +2
We study the effects of the spacial structure of localized losses in weakly-interacting fermionic quantum wires. We show that multiple dissipative impurities give rise to resonant…
