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…
Nonequilibrium transport through a singlet-triplet Anderson impurity
P. Roura Bas, A. A. Aligia
We study the Anderson model in which a configuration with a doublet is hybridized with another with a singlet and a triplet. We calculate the conductance through the system as a fu…
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…
Universal scaling in nonequilibrium transport through an Anderson impurity
Julian Rincon, A. A. Aligia, K. Hallberg
Using non-equilibrium renormalized perturbation theory, we calculate the conductance G as a function of temperature T and bias voltage V for an Anderson model, suitable for describ…
