Quantum Simulation of Semiconductor Excitons in Ultracold Dipolar Fermi Gases
Florian Hirsch, Oriana K. Diessel, RafaÅ OÅdziejewski +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, RafaÅ OÅdziejewski +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 -…
Super-Tonks-Girardeau Quench in the Extended Bose-Hubbard Model
Maciej Marciniak, Maciej Åebek, Jakub KopyciÅski +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…
Feshbach Resonances in Exciton-Charge-Carrier Scattering in Semiconductor Bilayers
Marcel Wagner, RafaÅ OÅdziejewski, 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…
Phase diagram and elementary excitations of strongly interacting droplets with non-local interactions
Maciej Åebek, Jakub KopyciÅski, 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…
