Tan's contact of a harmonically trapped one-dimensional Bose gas: strong-coupling expansion and conjectural approach at arbitrary interactions
Guillaume Lang, Patrizia Vignolo, Anna Minguzzi
We study Tan's contact, i.e. the coefficient of the high-momentum tails of the momentum distribution at leading order, for an interacting one-dimensional Bose gas subjected to a ha…
Ground-state energy and excitation spectrum of the Lieb-Liniger model : accurate analytical results and conjectures about the exact solution
Guillaume Lang, Frank Hekking, Anna Minguzzi
We study the ground-state properties and excitation spectrum of the Lieb-Liniger model, i.e. the one-dimensional Bose gas with repulsive contact interactions. We solve the Bethe-An…
High-momentum tails as magnetic structure probes for strongly-correlated fermionic mixtures in one-dimensional traps
Jean Decamp, Johannes Jünemann, Mathias Albert +3
A universal decay of the large-momentum tails of the momentum distribution, fixed by Tan's contact coefficients, constitutes a direct signature of strong correlations in a…
Localization transition in presence of cavity backaction
Katharina Rojan, Rebecca Kraus, Thomás Fogarty +3
We study the localization transition of an atom confined by an external optical lattice in a high-finesse cavity. The atom-cavity coupling yields an effective secondary lattice pot…
Thermal decoherence of a nonequilibrium polariton fluid
Sebastian Klembt, Petr Stepanov, Thorsten Klein +2
Exciton-polaritons constitute a unique realization of a quantum fluid interacting with its environment. Using Selenide based microcavities, we exploit this feature to warm up a pol…
Exact density profiles and symmetry classification for strongly interacting multi-component Fermi gases in tight waveguides
Jean Decamp, Pacome Armagnat, Bess Fang +3
We consider a mixture of one-dimensional strongly interacting Fermi gases up to six components, subjected to a longitudinal harmonic confinement. In the limit of infinitely strong…
