Spontaneous particle-hole symmetry breaking of correlated fermions on the Lieb lattice
Martin Bercx, Johannes S. Hofmann, Fakher F. Assaad +1
We study spinless fermions with nearest-neighbor repulsive interactions (- model) on the two-dimensional three-band Lieb lattice. At half-filling, the free electronic band st…
Kane-Mele-Hubbard model on the -flux honeycomb lattice
Martin Bercx, Martin Hohenadler, Fakher F. Assaad
We consider the Kane-Mele-Hubbard model with a magnetic flux threading each honeycomb plaquette. The resulting model has remarkably rich physical properties. In each spin secto…
Metamagnetism and Lifshitz Transitions in Models for Heavy Fermions
M. Bercx, F. F. Assaad
We investigate metamagnetic transitions in models for heavy fermions by considering the doped Kondo lattice model in two dimensions. Results are obtained within the framework of dy…
Fermi surface topology of the two-dimensional Kondo lattice model: a dynamical cluster approximation approach
L. C. Martin, M. Bercx, F. F. Assaad
We report the results of extensive dynamical cluster approximation calculations, based on a quantum Monte Carlo solver, for the two-dimensional Kondo lattice model. Our particular…
