Density wave propagation in a two-dimensional random dimer potential: From a single to a bipartite square lattice
(American Physical Society, 2020-01)
We study the propagation of a density perturbation in a weakly interacting boson gas confined on a lattice and in the presence of square dimerized impurities. Such a two-dimensional dual random dimer model (2D DRDM), ...
Incommmensurability and unconventional superconductor to insulator transition in the hubbard model with bond-charge interaction
(American Physical Society, 2007-12)
We determine the quantum phase diagram of the one-dimensional Hubbard model with bond-charge interaction X in addition to the usual Coulomb repulsion U>0 at half-filling. For large enough X
The metal-insulator transition in the paramagnetic Hubbard Model
(Elsevier Science, 2008-04)
We study the Mott transition in the Hubbard Model within the dynamical mean field theory (DMFT) approach. The DMFT equations are solved using the density matrix renormalization group technique. The densities of states for ...
Ephemeroptera of South AmericaEphemeroptera de América del Sur
(Pensoft Publishers, 2006)
The book covers all knwon 14 families, 103 genera and 470 species of the insect order Ephemeroptera from Continental South America. It includes updated keys to separate (in English and Spanish) families, genera and species ...
New records and combinations for Neotropical Leptophlebiidae (Ephemeroptera)
(Magnolia Press, 2005-09)
Several species of Leptophlebiidae (Atalophlebiinae) from South and Central America are given new generic combinations based on improved knowledge of the Leptophlebiidae of the region. These are Tikuna bilineata (Needham ...

Orbital-selective bad metals due to Hund’s rule and orbital anisotropy: A finite-temperature slave-spin treatment of the two-band Hubbard model
(American Physical Society, 2019-11)
We study the finiteerature properties of the half-filled two-band Hubbard model in the presence of Hund's rule coupling and orbital anisotropy. We use the mean-field treatment of the Z2 slave-spin theory with a finiteerature ...
Phase diagram of the asymmetric Hubbard model and an entropic chromatographic method for cooling cold fermions in optical lattices
(American Physical Society, 2012-08)
We study the phase diagram of the asymmetric Hubbard model (AHM), which is characterized by different values of the hopping for the two spin projections of a fermion or, equivalently, two different orbitals. This model is ...
