Many-body electronic structure and Kondo properties of cobalt-porphyrin molecules
Luis G. G. V. Dias da Silva, Murilo L. Tiago, Sergio E. Ulloa +2
We use a combination of first principles many-body methods and the numerical renormalization-group technique to study the Kondo regime of cobalt-porphyrin compounds adsorbed on a C…
Phonon-assisted tunneling and two-channel Kondo physics in molecular junctions
Luis G. Dias da Silva, Elbio Dagotto
The interplay between vibrational modes and Kondo physics is a fundamental aspect of transport properties of correlated molecular conductors. We present theoretical results for a s…
Transport properties and Kondo correlations in nanostructures: the time-dependent DMRG method applied to quantum dots coupled to Wilson chains
Luis G. G. V. Dias da Silva, F. Heidrich-Meisner, A. E. Feiguin +4
We apply the adaptive time-dependent Density Matrix Renormalization Group method (tDMRG) to the study of transport properties of quantum-dot systems connected to metallic leads. Fi…
Finite-temperature conductance signatures of quantum criticality in double quantum dots
Luis G. Dias da Silva, Kevin Ingersent, Nancy Sandler +1
We study the linear conductance through a double-quantum-dot system consisting of an interacting dot in its Kondo regime and an effectively noninteracting dot, connected in paralle…
Transmission in double quantum dots in the Kondo regime: Quantum-critical transitions and interference effects
Luis G. Dias da Silva, Nancy Sandler, Kevin Ingersent +1
We study the transmission through a double quantum-dot system in the Kondo regime. An exact expression for the transmission coefficient in terms of fully interacting many-body Gree…
Polarization and Aharonov-Bohm oscillations in quantum-ring magnetoexcitons
Luis G. Dias da Silva, Sergio E. Ulloa, Tigran V. Shahbazyan
We study interaction and radial polarization effects on the the absorption spectrum of neutral bound magnetoexcitons confined in quantum-ring structures. We show that the size and…
