Research Information

Research Overview

My main research activity is devoted to face the many-body problem using quantum (Bohm) trajectories in open systems. It has been recently demonstrated that these quantum trajectories provide a privileged framework to account for Coulomb and exchange correlations in time-dependent open (far from equilibrium) system scenarios. Within this framework I have been tackling the problem of current fluctuations in mesoscopic systems, I have delved into the formulation of an effective Hamiltonian for open classical and quantum systems driven far from equilibrium, and developed a model to include environmental electrostatic effects on mesoscopic electronic devices. Recently, I am beeing also involved in the formulation of the quantum measurement problem.
