Education: 

Gregory C. Psaltakis received his B.Sc. in Physics from the University of Athens, Greece (1978), the M.Sc. in Theoretical Physics, with "distinction", from the University of Essex (1979), and the Ph.D. in Theoretical Physics also from the University of Essex (1981), England, UK. His Ph.D. thesis was concerned with the applications of field theoretical methods in magnetism.

Career: 

During the time period 1981-1983 he was Research Associate (Post-doctoral fellow) at the Physics Division, Solid State Science Section, of the National Research Council of Canada, Ottawa, Canada. During 1983-1985 he was Maitre-Assistant at the Department of Theoretical Physics, University of Geneva, Switzerland. During 1986-1989 he worked as Researcher at the Institute of Electronic Structure and Laser (IESL), of the Research Center of Crete, Greece, in parallel with his military service. From 1989 until present he serves in a permanent position as Associate Professor at the Department of Physics, Condensed Matter Section, of the Univeristy of Crete, Greece.

Interests: 

His main research interests include, among other, the theoretical study of collective states occuring in Condensed Matter such as: magnetism, superconductivity, charge- and spin-density waves, Kondo effect, etc. The methods of Many-Body Theory, Monte-Carlo simulations, Renormalization Group and Scaling, are used in the analysis of these problems. Extensive use of the 1/N expansion method is also made in the study of localized spin systems such as the Heisenberg ferro- and anti-ferromagnets, in the systems with electron-phonon interactions, as well as in strongly interacting electron systems (Hubbard model, t-J and t-t'-J models) relevant to the High-Temperature Superconductivity phenomenon.
