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…
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…
Phase diagram and elementary excitations of strongly interacting droplets with non-local interactions
Maciej Łebek, Jakub Kopyciński, Wojciech Górecki +2
A one-dimensional bosonic gas with strong contact repulsion and attractive non-local interactions may form a quantum droplet with a flat-top density profile. We focus on a system i…
Superexchange Liquefaction of Strongly Correlated Lattice Dipolar Bosons
Ivan Morera, Rafał Ołdziejewski, Grigori E. Astrakharchik +1
We propose a mechanism for liquid formation in strongly correlated lattice systems. The mechanism is based on an interplay between long-range attraction and superexchange processes…
Beyond Gross-Pitaevskii equation for 1D gas: quasiparticles and solitons
Jakub Kopyciński, Maciej Łebek, Maciej Marciniak +3
Describing properties of a strongly interacting quantum many-body system poses a serious challenge both for theory and experiment. In this work, we study excitations of one-dimensi…
