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…
