Phases and dynamics of an impurity immersed in one-dimensional quantum droplets
Dimitrios Diplaris, Ilias A. Englezos, Friethjof Theel +2
We explore the ground-state properties of a single impurity immersed in a one-dimensional quantum droplet medium formed by a two-component Bose mixture. Relying on ab-initio simula…
Direct observation of long-range many-body coherence in quasi-one-dimensional attractive Bose gases
Hikaru Tamura, Sambit Banerjee, Rongjie Li +3
Macroscopic coherence is an important feature of quantum many-body systems exhibiting collective behaviors, with examples ranging from atomic Bose-Einstein condensates, and quantum…
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…
Collapse of a quantum vortex in an attractive two-dimensional Bose gas
Sambit Banerjee, Kai Zhou, Shiva Kant Tiwari +6
We experimentally and numerically study the collapse dynamics of a quantum vortex in a two-dimensional atomic superfluid following a fast interaction ramp from repulsion to attract…
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…
Crossover from attractive to repulsive induced interactions and bound states of two distinguishable Bose polarons
F. Theel, S. I. Mistakidis, P. Schmelcher
We study the impact of induced correlations and quasiparticle properties by immersing two distinguishable impurities in a harmonically trapped bosonic medium. It is found that when…
Artificial atoms from cold bosons in one dimension
Fabian Brauneis, Timothy G Backert, Simeon I Mistakidis +3
We investigate the ground-state properties of weakly repulsive one-dimensional bosons in the presence of an attractive zero-range impurity potential. First, we derive mean-field so…
Few-body correlations in two-dimensional Bose and Fermi ultracold mixtures
G. Bougas, S. I. Mistakidis, P. Giannakeas +1
Few-body correlations emerging in two-dimensional harmonically trapped mixtures, are comprehensively investigated. The presence of the trap leads to the formation of atom-dimer and…
Polaron Problems in Ultracold Atoms: Role of a Fermi Sea across Different Spatial Dimensions and Quantum Fluctuations of a Bose Medium
Hiroyuki Tajima, Junichi Takahashi, Simeon I. Mistakidis +2
The notion of a polaron, originally introduced in the context of electrons in ionic lattices, helps us to understand how a quantum impurity behaves when being immersed in and inter…
Quantum dynamical response of ultracold few boson ensembles in finite optical lattices to multiple interaction quenches
J. Neuhaus-Steinmetz, S. I. Mistakidis, P. Schmelcher
The correlated non-equilibrium quantum dynamics following a multiple interaction quench protocol for few-bosonic ensembles confined in finite optical lattices is investigated. The…
Coherent state path integrals in the continuum
G. Kordas, S. I. Mistakidis, A. I. Karanikas
We discuss the time-continuous path integration in the coherent states basis in a way that is free from inconsistencies. Employing this notion we reproduce known and exact results…
