The cumulant Green's functions method for the single impurity Anderson model
T. M. Sobreira, T. O. Puel, M. A. Manya +5
Using the cumulant Green's functions method (CGFM), we study the single impurity Anderson model (SIAM). The CGFM starting point is a diagonalization of the SIAM Hamiltonian express…
Ground state of a mixture of SU() fermions and scalar bosons
J. Silva-Valencia, J. J. Mendoza-Arenas
We explore a system composed of scalar bosons and SU() fermions in one dimension. Considering only local intra- and interspecies interactions, the system is described by the Bos…
Spin-selective insulators
J. Silva-Valencia
Spin-selective insulators emerge in systems composed of fermions with two internal degrees of freedom and another carrier, which could be fermionic or bosonic. These insulators are…
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…
