Probing nonequilibrium transport and density profiles in tilted interacting fermion chains with local reservoirs
Andrea Nava, N. Aucar Boidi, Reinhold Egger +2
We investigate how local particle reservoirs can probe transport and density profiles in tilted spinless fermion chains with nearest-neighbor interactions. Using finite-chain Lindb…
Wannier-Stark localization, confinement and edge states
N. Aucar Boidi, A. Aharony, O. Entin-Wohlman +1
The boundary between a system's bulk and the vacuum can be modeled by a potential which confines the electrons to the bulk. Here we present the example of the Wannier-Stark linear…
A density matrix renormalization group approach to quantum point contacts
Nair Aucar Boidi, Mikhail Kiselev
Using the density matrix renormalization group (DMRG) combined with the correction-vector method, we investigate the competition between an harmonic potential and repulsive interac…
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…
Determination of superexchange interactions for the CuO chains in LiCuO
N. Aucar Boidi, Christian Helman, Y. Núñez-Fernández +2
Starting from \textit{ab-initio} calculations, we derive a five-band Hubbard model to describe the CuO chains of LiCuO. This model is further simplified to a low-energy…
