Fast dynamical control of quantum droplets via Feshbach resonances
Jing Li, Thomas Fogarty, Thomas Busch +1
We propose a variational shortcut-to-adiabaticity scheme for the fast dynamical control of one-dimensional quantum droplets in ultracold Bose-Bose mixtures. The control is implemen…
Mobile impurity interacting with a Hubbard chain and the role of Friedel oscillations
Felipe Isaule, Abel Rojo-Francàs, 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…
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 (BECs) are typically prone to collapse under strong interspecies attraction, it has been shown that higher-order fluctuation correctio…
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…
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…
Emergence of nonequilibrium Lieb excitations in periodically driven strongly interacting bosons
Hoshu Hiyane, Giedrius Žlabys, Thomas Busch +1
We study the exact nonequilibrium spectral function of a gas of strongly correlated Tonks-Girardeau bosons subjected to a strong periodic drive. Utilizing the theory of Floquet spe…
Shortcuts to Adiabaticity in Anisotropic Bose-Einstein Condensates
Chinmayee Mishra, Thomas Busch, Thomás Fogarty
We propose shortcut to adiabaticity protocols for Bose-Einstein condensates trapped in generalized anisotropic harmonic traps in three dimensions. These protocols enable high-fidel…
The Lieb excitations and topological flat mode of spectral function of Tonks-Girardeau gas in Kronig-Penney potential
Wen-Bin He, Giedrius Žlabys, Hoshu Hiyane +2
Lieb excitations are fundamental to the understanding of the low energy behaviour of many-body quantum gases. Here we study the spectral function of a Tonks-Girardeau gas in a fini…
Bose-Fermi -polaron state emergence from correlation-mediated blocking of phase separation
Felipe Gómez-Lozada, Hoshu Hiyane, Thomas Busch +1
We study fermionic impurities in a one-dimensional lattice bosonic bath at unit filling. Using DMRG and mixed boundary conditions-periodic for bosons, open for fermions -- we f…
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…
Engineering impurity Bell states through coupling with a quantum bath
Tran Duong Anh-Tai, Thomás Fogarty, Sergi de María-García +2
We theoretically demonstrate the feasibility of creating Bell states in multi-component ultra-cold atomic gases by solely using the ability to control the inter-particle interactio…
Phases and dynamics of few fermionic impurities immersed in two-dimensional boson droplets
Jose Carlos Pelayo, Thomás Fogarty, Thomas Busch +1
We unravel the ground state properties and emergent non-equilibrium dynamics of a mixture consisting of a few spin-polarized fermions embedded in a two-dimensional bosonic quantum…
Quantum soliton-trains of strongly correlated impurities in Bose-Einstein condensates
Hoshu Hiyane, Thomas Busch, Thomás Fogarty
Strongly correlated impurities immersed in a Bose-Einstein condensate (BEC) can form a periodic structure of tightly localized single atoms due to competing inter- and intra-specie…
Sharp crossover from composite fermionization to phase separation in mesoscopic mixtures of ultracold bosons
M. A. Garcia-March, B. Julia-Diaz, G. E. Astrakharchik +3
We show that a two-component mixture of a few repulsively interacting ultracold atoms in a one-dimensional trap possesses very different quantum regimes and that the crossover betw…
