Momentum-space dynamics of Dirac quasiparticles in correlated random potentials: Interplay between dynamical and Berry phases
Kean Loon Lee, Benoît Grémaud, Christian Miniatura
We consider Dirac quasi-particles, as realized with cold atoms loaded in a honeycomb lattice or in a -flux square lattice, in the presence of a weak correlated disorder such tha…
From antiferromagnetic order to magnetic textures in the two dimensional Fermi Hubbard model with synthetic spin orbit interaction
Jiří Minář, Benoît Grémaud
We study the interacting Fermi-Hubbard model in two spatial dimensions with synthetic gauge coupling of the spin orbit Rashba type, at half-filling. Using real space mean field the…
Competing Supersolid and Haldane Insulator phases in the extended one-dimensional bosonic Hubbard model
G. G. Batrouni, R. T. Scalettar, V. G. Rousseau +1
The Haldane Insulator is a gapped phase characterized by an exotic non-local order parameter. The parameter regimes at which it might exist, and how it competes with alternate type…
Dirac fields in curved spacetime as Fermi-Hubbard model with non unitary tunnelings
Jiří Minář, Benoît Grémaud
In this article we show that a Dirac Hamiltonian in a curved background spacetime can be interpreted, when discretized, as a tight binding Fermi-Hubbard model with non unitary tunn…
