Mobile impurity interacting with a Hubbard chain and the role of Friedel oscillations
Felipe Isaule, Abel Rojo-Francà s, Duc Tuan Hoang +3
This work examines a mobile impurity interacting with a bath of a few spin- and spin- fermions in a small one-dimensional open lattice system. We study ground…
Droplet-gas phases and their dynamical formation in particle imbalanced mixtures
Jose Carlos Pelayo, George A. Bougas, Thomás Fogarty +2
We explore the ground state phase diagram and nonequilibrium dynamics of genuine two-component particle-imbalanced droplets in both isotropic and anisotropic three-dimensional conf…
Correlated decoherence and thermometry with mobile impurities in a 1D Fermi gas
Sindre Brattegard, Thomás Fogarty, Thomas Busch +1
We theoretically investigate the correlated decoherence dynamics of two mobile impurities trapped within a gas of ultracold fermionic atoms. We use a mean-field approximation to se…
Quantum droplets in one-dimensional mixtures of quasi Bose-Einstein condensates and Tonks-Girardeau gases
Wen-Bin He, Su Yi, Thomas Busch
While binary atomic Bose-Einstein condensates are typically prone to collapse under strong interspecies attraction, it has been shown that higher-order fluctuation corrections, kno…
Condensate-mediated dimerization of impurities in atomic BECs
Hoshu Hiyane, Thomás Fogarty, Jose Carlos Pelayo +1
We show that strongly correlated impurities confined in an optical lattice can form localized, molecule-like dimer states in the presence of a Bose-Einstein condensate (BEC). By sy…
Phases and dynamics of quantum droplets in the crossover to two-dimensions
Jose Carlos Pelayo, George Bougas, Thomás Fogarty +2
We explore the ground states and dynamics of ultracold atomic droplets in the crossover region from three to two dimensions by solving the two-dimensional and the quasi two-dimensi…
