Mass imbalance in the ionic Hubbard model: a DRMG study
D. C. Padilla-González, R. Franco, J. Silva-Valencia
We investigated the ionic Hubbard model with mass imbalance in one dimension, using the density matrix renormalization group method. This model exhibits a band insulator phase and…
Universality and thermoelectric transport properties of quantum dot systems
D. F. Aranguren-Quintero, E. Ramos, J. Silva-Valencia +3
We discuss the temperature-dependent thermoelectric transport properties of semiconductor nanostructures comprising a quantum dot coupled to quantum wires: the thermal dependence o…
Spin-selective insulators in Bose-Fermi mixtures
R. Guerrero-Suarez, J. J. Mendoza-Arenas, R. Franco +1
We investigate an imbalanced mixture composed of two-color fermions and scalar bosons in the hard-core limit, considering repulsive and attractive interspecies and intraspecies int…
Mixture of scalar bosons and two-color fermions in one dimension: Superfluid-insulator transitions
R. Avella, J. J. Mendoza-Arenas, R. Franco +1
Superfluid-insulator transitions in a one-dimensional mixture of two-color fermions and scalar bosons are studied within the framework of the Bose-Fermi-Hubbard model. Zero-tempera…
Spinor bosons in optical superlattices: a numerical study
G. J. Cruz, R. Franco, J. Silva-Valencia
The ground state of spin-1 ultracold bosons trapped in a periodic one-dimensional optical superlattice is studied. The two sites of the unit cell have an energy shift between them,…
