Dimensional crossover on multileg attractive- Hubbard ladders
Anastasia Potapova, Ian Pilé, Tian-Cheng Yi +2
We study the ground state properties of a polarized two-component Fermi gas on multileg attractive- Hubbard ladders. Using exact diagonalization and density matrix renormalizati…
Mobile impurity in a one-dimensional quantum gas: Exact diagonalization in the Bethe Ansatz basis
Evgeni Burovski, Oleksandr Gamayun, Oleg Lychkovskiy
We consider a mobile impurity particle injected into a one-dimensional quantum gas. The time evolution of the system strongly depends on whether the mass of the impurity and the ma…
Phase diagrams of polarized ultra-cold gases on attractive-U Hubbard ladders
E. Burovski, R. Sh. Ikhsanov, A. A. Kuznetsov +1
We consider a quasi-one-dimensional model of a two-component Fermi gas at zero temperature on one, two and three-leg attractive-U Hubbard ladders. We construct the grand canonical…
The impact of the injection protocol on an impurity's stationary state
Oleksandr Gamayun, Oleg Lychkovskiy, Evgeni Burovski +3
We examine stationary state properties of an impurity particle injected into a one-dimensional quantum gas. We show that the value of the impurity's end velocity lies between zero…
Momentum relaxation of a mobile impurity in a one-dimensional quantum gas
E. Burovski, V. Cheianov, O. Gamayun +1
We investigate the time evolution of the momentum of an impurity atom injected into a degenerate Tonks-Girardeau gas. We establish that given an initial momentum the impurity…
Néel temperature and thermodynamics of the half-filled 3D Hubbard model by Diagrammatic Determinant Monte Carlo
E. Kozik, E. Burovski, V. W. Scarola +1
We study thermodynamics of the 3D Hubbard model at half filling on approach to the Néel transition by means of large-scale unbiased Diagrammatic Determinant Monte Carlo simulations…
Multimer formation in 1D two-component gases and trimer phase in the asymmetric attractive Hubbard model
Guillaume Roux, Evgeni Burovski, Thierry Jolicoeur
We consider two-component one-dimensional quantum gases at special imbalanced commensurabilities which lead to the formation of multimer (multi-particle bound-states) as the domina…
Fermionic trimers in spin-dependent optical lattices
Giuliano Orso, Evgeni Burovski, Thierry Jolicoeur
We investigate the formation of three-body bound states (trimers) in two-component Fermi gases confined in one dimensional optical lattice with spin-dependent tunneling rates. The…
Thermodynamics of the 3D Hubbard model on approach to the Neel transition
S. Fuchs, E. Gull, L. Pollet +4
We study the thermodynamic properties of the 3D Hubbard model for temperatures down to the Neel temperature using cluster dynamical mean-field theory. In particular we calculate th…
Quantitative Determination of Temperature in the Approach to Magnetic Order of Ultracold Fermions in an Optical Lattice
Robert Jördens, Leticia Tarruell, Daniel Greif +12
We perform a quantitative simulation of the repulsive Fermi-Hubbard model using an ultracold gas trapped in an optical lattice. The entropy of the system is determined by comparing…
Luttinger liquid of trimers in Fermi gases with unequal masses
Giuliano Orso, Evgeni Burovski, Thierry Jolicoeur
We investigate one dimensional attractive Fermi gases in spin-dependent optical lattices. We show that three-body bound states - "trimers" - exist as soon as the two tunneling rate…
Multi-particle composites in density-imbalanced quantum fluids
Evgeni Burovski, Giuliano Orso, Thierry Jolicoeur
We consider two-component one-dimensional quantum gases with density imbalance. While generically such fluids are two-component Luttinger liquids, we show that if the ratio of the…
