The physics of heavy fermions
 
Heavy-fermion materials consist of arrays of magnetic impurities embedded in metallic environments. These compounds are characterized by a very large quasiparticle mass. They exhibit a host of fascinating quantum phase transitions, that we will discuss in detail during this lecture. Emphasis will be placed on numerical approaches based on the U(1) gauge theory formulation of the Kondo lattice model.

Speaker Professor Fakher Assaad

Theoretische Physik I Julius-Maximilians-Universitaet Würzburg, Germany

Professor Assaad receive his PhD in Physics at the ETH Zürich in 1991. He worked as postdoctoral fellow at University of Würzburg from 1991-1993, University of Tokyo from 1994-1995, University of California, and Santa-Barbara at 1996-1997. He started his assistant position at the university of Stuttgart in 1997 and worked as Heisenberg fellow from 2001-2003. He then worked as professor (C3) at the University of Würzburg from 2003. In 2009, he became co-spokesman of the research unit FOR1162, Electron induced phenomena in surfaces and interfaces with tunable interactions and spokesman of the research unit FOR1807, Advanced Computational Methods for Strongly Correlated Quantum Systems, in 2011. His project proposal for computational resources was awarded the John von Neumann Exzellenz-Projekt 2012 prize. His research interest includes: computational quantum many body physics, strongly correlated electron systems, and development and investigation of numerical tools.
