Pairing and pair superfluid density in one-dimensional Hubbard models
B. Grémaud, G. G. Batrouni
We use unbiased computational methods to elucidate the onset and properties of pair superfluidity in two-species fermionic and bosonic systems with onsite interspecies attraction l…
Nonlinear two-photon Rabi-Hubbard model: superradiance and photon/photon-pair Bose-Einstein condensate
Shifeng Cui, B. Grémaud, Wenan Guo +1
We study the ground state phase diagram of a nonlinear two-photon Rabi-Hubbard (RH) model in one dimension using quantum Monte Carlo (QMC) simulations and density matrix renormaliz…
Negative delta- noise in the Fractional Quantum Hall effect
J. Rech, T. Jonckheere, B. Grémaud +1
We study the current correlations of fractional quantum Hall edges at the output of a quantum point contact (QPC) subjected to a temperature gradient. This out-of-equilibrium situa…
Two-photon Rabi-Hubbard and Jaynes-Cummings-Hubbard models: photon pair superradiance, Mott insulator and normal phases
Shifeng Cui, F. Hébert, B. Grémaud +3
We study the ground state phase diagrams of two-photon Dicke, the one-dimensional Jaynes-Cummings-Hubbard (JCH), and Rabi-Hubbard (RH) models using mean field, perturbation, quantu…
Pairing and superconductivity in the flat band: Creutz lattice
Rubem Mondaini, G. George Batrouni, Benoît Grémaud
We use unbiased numerical methods to study the onset of pair superfluidity in a system that displays flat bands in the noninteracting regime. This is achieved by using a known exam…
Topological Insulators in the Honeycomb Lattice
Ulrike Bornheimer, Christian Miniatura, Benoît Grémaud
We investigate realizations of topological insulators with spin-1 bosons loaded in a honeycomb optical lattice and subjected to a spin-orbit coupling - a situation which ca…
