Quantum Simulation of Semiconductor Excitons in Ultracold Dipolar Fermi Gases
Florian Hirsch, Oriana K. Diessel, Rafał Ołdziejewski +1
Inspired by the progress on the study of exciton physics in atomically thin transition metal dichalcogenide (TMD) semiconductors, we investigate the formation of analogs of exciton…
Emergent Fermi polarons in Dirac materials
Xin Chen, Eugen Dizer, Rafał Ołdziejewski +3
We investigate band-structure effects on the absorption spectra of quantum impurities in Dirac materials. We uncover the formation of novel quasiparticles -- Dirac-Fermi polarons -…
Fermionization and collective excitations of 1D polariton lattices
Johannes Knörzer, Rafał Ołdziejewski, Puneet A. Murthy +1
We theoretically demonstrate that the hallmarks of correlation and fermionization in a one-dimensional exciton-polaritons gas can be observed with state-of-the-art technology. Our…
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…
Super-Tonks-Girardeau Quench in the Extended Bose-Hubbard Model
Maciej Marciniak, Maciej Łebek, Jakub Kopyciński +3
We investigate the effect of a quench from a one-dimensional gas with strong and repulsive local interactions to a strongly attractive one, known as the super-Tonks-Girardeau effec…
Impurity-induced pairing in two-dimensional Fermi gases
Ruipeng Li, Jonas von Milczewski, Atac Imamoglu +2
We study induced pairing between two identical fermions mediated by an attractively interacting quantum impurity in two-dimensional systems. Based on a Stochastic Variational Metho…
