Exact Analysis of a One-Dimensional Yang-Gaudin Model with Two-Body Loss
Ryutaro Katsuta, Shun Uchino
We show that the one-dimensional Yang-Gaudin model with two-body loss remains exactly solvable irrespective of whether constituent particles are bosons or fermions. By relating the…
Edge-controlled non-Hermitian skin effect in the modified Haldane model
Nobuhiro Ito, Shun Uchino
The hybrid skin-topological effect (HSTE) arises from the interplay between the non-Hermitian skin modes and topologically protected edge states. Here, we investigate the HSTE asso…
Quantum Point Contact with Local Two-body Loss
Kensuke Kakimoto, Shun Uchino
Motivated by recent advances in ultracold atomic gas experiments, we investigate a two-terminal mesoscopic system in which two-body loss occurs locally at the center of a one-dimen…
Cavity-mediated charge and pair-density waves in a unitary Fermi gas
Timo Zwettler, Filip MarijanoviÄ, Tabea Bühler +7
Coherent light-matter interactions between a quantum gas and light in a high-finesse cavity can drive self-ordering phase transitions. To date, such phenomena have involved exclusi…
