Low-energy structure and topology of the two-band Hubbard-Kanamori model
Nayara G. Gusmão, Germán Blesio, Armando Aligia +3
We investigate the Mott transition in a two-band Hubbard-Kanamori model using Dynamical Mean-Field Theory (DMFT) with the Density Matrix Renormalization Group (DMRG) and the Numeri…
Crossover from Wannier-Stark localization to charge density waves for interacting spinless fermions in one dimension
Nair Aucar Boidi, Amnon Aharony, Ora Entin-Wohlman +2
We study spinless fermions on a finite chain with nearest-neighbor repulsion and in the presence of a Wannier-Stark linearly-varying electric field potential. In the absence of the…
Phase diagram and topology of the XXZ chain with alternating bonds and staggered magnetic field
B. F. Márquez, N. Aucar Boidi, K. Hallberg +1
The XXZ spin-half chain has Heisenberg exchange interactions () in the () direction. The model has a transition from the spin-fluid phase for $-J_\perp < J_…
Unconventional correlated metallic behavior due to interorbital Coulomb interaction
N. Aucar Boidi, A. P. Kampf, K. Hallberg
We study the non-degenerate one dimensional two-orbital Hubbard model with interorbital Coulomb interaction. By means of the density-matrix renormalization group technique, we calc…
Coexistence of insulating phases in confined fermionic chains with a Wannier-Stark potential
N. Aucar Boidi, K. Hallberg, A. Aharony +1
We study fermions on a finite chain, interacting repulsively when residing on the same and on nearest-neighbor sites, and subjected to a Wannier-Stark linearly-varying potential. U…
Metal-insulator transition in the hybridized two-orbital Hubbard model revisited
Y. Nunez-Fernandez, K. Hallberg
In this work we study the two-orbital Hubbard model on a square lattice in the presence of hybridization between nearest-neighbor orbitals and a crystal-field splitting. We use a h…
