Scanning tunneling microscopy of adsorbed molecules on metalic surfaces for nearly localized atomic states
M. Romero, A. A. Aligia
We consider a Hubbard-Anderson model which describes localized orbitals in five different sites hybridized both among themselves and with a continuum of extended states. A square p…
Microcavity exciton-polariton mediated Raman scattering: Experiments and theory
A. Bruchhausen, L. M. Leon Hilario, A. A. Aligia +4
We studied the intensity of resonant Raman scattering due to optical phonons in a planar II-VI-type semiconductor microcavity in the regime of strong coupling between light and mat…
Photoluminiscence of a quantum dot hybridized with a continuum
L. M. Leon Hilario, A. A. Aligia
We calculate the intensity of photon emission from a trion in a single quantum dot, as a function of energy and gate voltage, using the impurity Anderson model and variational wave…
Pseudogap opening and formation of Fermi arcs as an orbital-selective Mott transition in momentum space
M. Ferrero, P. S. Cornaglia, L. De Leo +3
We present an approach to the normal state of cuprate superconductors which is based on a minimal cluster extension of dynamical mean-field theory. Our approach is based on an effe…
Dynamical mean field theory of an effective three-band model for NaCoO
A. Bourgeois, A. A. Aligia, M. J Rozenberg
We derive an effective Hamiltonian for highly correlated states centered at the Co sites of NaCoO. The essential ingredients of the model are an O mediated hopping…
Conductance through strongly interacting rings in a magnetic field
Julián Rincón, A. A. Aligia, K. Hallberg
We study the conductance through finite Aharonov-Bohm rings of interacting electrons weakly coupled to non-interacting leads at two arbitrary sites. This model can describe an arra…
