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…
Quench dynamics in topologically non-trivial quantum many-body systems
Sarika Sasidharan Nair, Giedrius Žlabys, Wen-Bin He +2
We investigate the nonequilibrium dynamics of a groundstate fermionic many body gas subjected to a quench between parameter regimes of a topologically nontrivial Hamiltonian. By fo…
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…
High fidelity control of a many-body Tonks--Girardeau gas with an effective mean-field approach
Muhammad S. Hasan, Thomás Fogarty, Jing Li +2
Shortcuts to adiabaticity (STA) are powerful tools that can be used to control quantum systems with high fidelity. They work particularly well for single particle and non-interacti…
Dynamical invariant based shortcut to equilibration in open quantum systems
Mohamed Boubakour, Shimpei Endo, Thomás Fogarty +1
We propose using the dynamical invariant also known as the Lewis-Riesenfeld invariant, to speed-up the equilibration of a driven open quantum system. This allows us to reverse engi…
