Theory and Modeling


The Hauser group is yet a small, but hopefully fast growing theory group of Molecular Physics and Quantum Chemistry enthusiasts embedded in an interesting environment of experimentalists: We are part of the Institute of Experimental Physics at the Graz University of Technology, a rather unconventional but advantageous setup, which led to a whole series of joint publications in the field of metallic cluster physics and molecular spectroscopy with the group of Prof. Wolfgang Ernst.

A brief overview of our current research and topics of the past is given below. For more details on our research and a list of publications please have a look at our Group Homepage.

  • First principles studies in surface chemistry and cluster physics
    • Gas adsorption 
    • Thermochemistry, Reaction Dynamics
  • Cluster properties modeling
    • Surface Diffusion processes
    • Rayleigh breakup
    • Metallic nanowires and core-shell-systems
  • Alkane dehydrogenation via Pt and Pt-alloy nanoparticles
    • C-H bond activation
    • Descriptors for catalytic activity and selectivity
  • New materials for molecular sieving, gas storage and separation 
    • Nanoporous graphene sheets 
    • Hydrogen, carbon dioxide and methane sequestration
    • Separation of bosonic from fermionic helium
    • Membrane-based chiral separation
  • Quantum chemical studies of weakly interacting systems such as
