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…
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…
Linear rotor in an ideal Bose gas near the threshold for binding
Tibor Dome, Artem G. Volosniev, Areg Ghazaryan +3
We study a linear rotor in a bosonic bath within the angulon formalism. Our focus is on systems where isotropic or anisotropic impurity-boson interactions support a shallow bound s…
Phase diagram for strong-coupling Bose polarons
Arthur Christianen, J. Ignacio Cirac, Richard Schmidt
Important properties of complex quantum many-body systems and their phase diagrams can often already be inferred from the impurity limit. The Bose polaron problem describing an imp…
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…
Bose polaron interactions in a cavity-coupled monolayer semiconductor
Li Bing Tan, Oriana K. Diessel, Alexander Popert +3
The interaction between a mobile quantum impurity and a bosonic bath leads to the formation of quasiparticles, termed Bose polarons. The elementary properties of Bose polarons, suc…
