Research interests
Theoretical Condensed Matter Physics with interest in many-body and few-body nanostructure systems. Optical and electronic properties of quantum dots by applying non-perturbative formalisms from the Quantum Theory of Finite Systems. His activity has a strong component of computational physics.
- Electronic excitations and optical properties of hybrid systems, organic molecule coupled to a semiconductor nanoparticle, relevant to photovoltaic applications.
- Electronic excitations of charged semiconductor quantum dots. Mean field, Configuration Interaction and exact diagonalization calculations.
- Optical spectroscopy of quantum dots: intra- and interband optical absorption, photoluminescence (PL), and electronic Raman scattering.
- Giant Dipole Resonance (GDR) in microcavity-quantum dot systems.
- Standardization of software for Computational Condensed Matter and Quantum Chemistry. Implementation several numerical methods for many-body physics (Hartree-Fock, RPA, Configuration Interaction (CI), Quantum Monte Carlo).
