Prof. Dr. Rodolfo A. Jalabert
Condensed Matter Physics
External Senior Fellow
Januar - Juli 2015
Rodolfo Jalabert obtained his engineer degree from the Universidad de la República (Uruguay) in 1983 and his Ph.D. in Physics from the University of Maryland in 1989. He performed post-doctoral work between 1989 and 1994 at Yale University, the Commissariat à l’Energie Atomique (Saclay), and the Institut de Physique Nucléaire d’Orsay. Since 1994 he is a Professor of Physics at the Université de Strasbourg and research staff of the Institut de Physique et Chimie des Matériaux de Strasbourg. He has been member of the Institut universitaire de France from 1998 to 2003.
Prof. Jalabert is a theoretician of Condensed Matter Physics, specialized in the study of quantum mesosocopic systems. The centers of interest of his research include: the quantum chaos signatures in low-temperature transport of micro and nano-structures, the conductance through disordered and strongly correlated systems, the application of random matrix theories to quantum transport, the optical properties and collective excitations of nano-objects, the spin relaxation in doped semiconductors and semiconductor quantum dots, as well as the decoherence and reversibility in small quantum systems.

Coherence of charge transport in finite disordered systems
The interplay between coherent and incoherent transport in finite disordered systems will be studied by developing different models that are able to account for the process observed in photosynthetic complexes. In particular, it will be addressed the understanding of how the electronic excitations travel in a finite-size disordered system, on the combined effects of disorder and Coulomb interactions in the exciton transport capable of inducing a tendency towards delocalization in finite systems, as well as on the coupling to the environment that results in a progressive loss of quantum coherence with the corresponding suppression of interference effects.
