Finite-temperature properties of hard-core bosons confined on one-dimensional optical lattices
Marcos Rigol
We present an exact study of the finite-temperature properties of hard-core bosons (HCB's) confined on one-dimensional optical lattices. Our solution of the HCB problem is based on…
Comment on "Novel Superfluidity in a Trapped Gas of Fermi Atoms with Repulsive Interaction Loaded on an Optical Lattice"
M. Rigol, S. R. Manmana, A. Muramatsu +3
In a recent letter Machida et al. [Phys. Rev. Lett. 93, 200402 (2004)] concluded that in a trapped gas of fermions with repulsive interactions a superfluid phase appears around the…
Numerical simulations of strongly correlated fermions confined in 1D optical lattices
Marcos Rigol, Alejandro Muramatsu
On the basis of quantum Monte Carlo (QMC) simulations we study the formation of Mott domains in the one-dimensional Hubbard model with an additional confining potential. We find ev…
Fermionization in an expanding 1D gas of hard-core bosons
Marcos Rigol, Alejandro Muramatsu
We show by means of an exact numerical approach that the momentum distribution of a free expanding gas of hard-core bosons on a one-dimensional lattice approaches to the one of non…
Ground-state properties of hard-core bosons confined on one-dimensional optical lattices
Marcos Rigol, Alejandro Muramatsu
We study the ground-state properties of hard-core bosons trapped by arbitrary confining potentials on one-dimensional optical lattices. A recently developed exact approach based on…
Emergence of quasi-condensates of hard-core bosons at finite momentum
Marcos Rigol, Alejandro Muramatsu
An exact treatment of the non-equilibrium dynamics of hard-core bosons on one-dimensional lattices shows that, starting from a pure Fock state, quasi-long-range correlations develo…
