Luis Foà Torres
I’m a condensed matter physicist with over 15 years of experience in the field of quantum transport, modeling and simulation of nanomaterials and nanodevices. After working in Italy, France and Germany and Argentina, I joined the Department of Physics (FCFM) of the University of Chile. Here I lead an interdisciplinary team (physicists and chemists) working on the electronic and optoelectronic properties of nanomaterials and nanodevices.
Most of my research is focused on the electrical (quantum transport) and opto-electronic properties of two dimensional nanomaterials (graphene-based, TMDCs) 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. The idea is generating and tuning topologically protected states by using a laser field.
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 (experimental, see for example this paper). For more details on my research you can also visit my publications page or check the following links written for a more general public.
