Magnetic Phase Transition in the Ground-State Phase Diagram of Binary Bose Gases in Optical Lattices
Laurent de Forges de Parny, Valéry Rousseau
We investigate the ground-state phase diagram of interacting binary Bose gases trapped in two-dimensional optical lattices by means of quantum Monte Carlo simulations. Our simulati…
Scaling properties of the Tan's contact: embedding pairs and correlation effect in the Tonks limit
F. T. Sant'Ana, F. Hébert, V. Rousseau +2
We study the Tan's contact of a one dimensional quantum gas of N repulsive identical bosons confined in a harmonic trap at finite temperature. This canonical ensemble framework cor…
The superfluid density in continuous and discrete spaces: Avoiding misconceptions
V. G. Rousseau
We review the concept of superfluidity and, based on real and thought experiments, we use the formalism of second quantization to derive expressions that allow the calculation of t…
Optimized Confinement of Fermions in Two Dimensions
J. D. Cone, S. Chiesa, V. R. Rousseau +2
One of the challenging features of studying model Hamiltonians with cold atoms in optical lattices is the presence of spatial inhomogeneities induced by the confining potential, wh…
Directed update for the Stochastic Green Function algorithm
V. G. Rousseau
In a recent publication (Phys. Rev E 77, 056705 (2008)),we have presented the stochastic Green function (SGF) algorithm, which has the properties of being general and easy to apply…
Canonical Trajectories and Critical Coupling of the Bose-Hubbard Hamiltonian in a Harmonic Trap
G. G. Batrouni, H. R. Krishnamurthy, K. W. Mahmud +2
Quantum Monte Carlo (QMC) simulations and the Local Density Approximation (LDA) are used to map the constant particle number (canonical) trajectories of the Bose Hubbard Hamiltonia…
