Luis Foà Torres
I’m a condensed matter physicist with over 10 years of experience in the field of quantum transport, modeling and simulation of nanomaterials and nanodevices. After working in Italy, France and Germany, I led an interdisciplinary team (physicists and chemists) with three PhD students and a postdoc working on the electronic and optoelectronic properties of nanomaterials and nanodevices at the National University of Cordoba (UNC) in Argentina. Recently, I moved to the Department of Physics (FCFM) of the University of Chile.
Most of my research is focused on the electrical (quantum transport) and opto-electronic properties of two dimensional nanomaterials (graphene-based, MoS2,…) and topological insulators. In particular, my efforts are aimed to the understanding and control of quantum effects arising from time-dependent fields, many-body interactions and decoherence.
At the moment one of the questions that fuels my attention has to do with a new phase of (non-equilibrium) topological insulators (topological insulators are fascinating new materials exhibiting a bulk bandgap but with conducting edge states which are robust to disorder and other perturbations). The idea is to generate and tune topologically protected states by using a laser field as here.
Other research interests include the generation of a directed current at zero bias through quantum interference (quantum pumping) and the synthesis and Raman characterization of graphene multilayers by liquid-phase exfoliation.
