Feshbach Resonances in Exciton-Charge-Carrier Scattering in Semiconductor Bilayers
Marcel Wagner, Rafał Ołdziejewski, Félix Rose +4
Feshbach resonances play a vital role in the success of cold atoms investigating strongly-correlated physics. The recent observation of their solid-state analog in the scattering o…
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…
Dynamics of atoms within atoms
S. Tiwari, F. Engel, M. Wagner +3
Recent experiments with Bose-Einstein condensates have entered a regime in which thousands of ground-state condensate atoms fill the Rydberg-electron orbit. After the excitation of…
Tunable Feshbach resonances and their spectral signatures in bilayer semiconductors
Clemens Kuhlenkamp, Michael Knap, Marcel Wagner +2
Feshbach resonances are an invaluable tool in atomic physics, enabling precise control of interactions and the preparation of complex quantum phases of matter. Here, we theoretical…
Probing Nonlocal Spatial Correlations in Quantum Gases with Ultra-long-range Rydberg Molecules
J. D. Whalen, S. K. Kanungo, R. Ding +7
We present photo-excitation of ultra-long-range Rydberg molecules as a probe of spatial correlations in quantum gases. Rydberg molecules can be created with well-defined internucle…
Topological invariants in dissipative extensions of the Su-Schrieffer-Heeger model
Felix Dangel, Marcel Wagner, Holger Cartarius +2
We investigate dissipative extensions of the Su-Schrieffer-Heeger model with regard to different approaches of modeling dissipation. In doing so, we use two distinct frameworks to…
