Anton Paar Wissenschaftspreis für Physik 2014: Dipl. Ing. Dr. Rene Hammer

Donnerstag, 16.10.2014

This year's Anton Paar Wissenschaftspreis für Physik" was awarded to Dipl. Ing. Dr. Rene Hammer upon the 64th Annual Meeting of the the Austrian Physical Society (ÖPG). This award is given to the best dissertation in the field of solid state physics.

Dr. Rene Hammer's PhD Thesis entitled "Dynamics of Dirac Fermions" (Physics Department, Univ. of Graz, Oct. 2013, supervisor: Walter Pötz, funding: FWF I-395) deals with an innovative numerical scheme which allows the simulation of Dirac fermions on a lattice without the occurrence of fermion doubling. Although the latter had been a long-standing unsolved problem in high-energy physics the motivation for this thesis was the experimental realization of metallic Dirac-fermion surface states in topological insulators. This scheme, which was formulated explicitly in 1+1, 2+1, and 3+1 space-time dimensions was used in numerical studies of coherent single-particle dynamics in electromagnetically textured topological insulator surfaces. Simulations performed within this thesis included, among other things, Klein tunneling, superlensing, the dynamics in ferromagnetic vortices, and the propagation of domain-wall fermions. Structures which serve as one-way Dirac fermion wave guides and interferometers were proposed and evaluated.

Rene Hammer was born in Graz and received a diploma degree in physics from the Technical University of Graz before joining the Solid State Theory group of Walter Pötz at the Karl Franzens University in Graz. He currently holds a research position at the Materials Center Leoben (MCL).
