Study of Technische Physik at the TH Graz.
Since 1974 Assistent at the Institut for Theoretical Physics in
Several stays outside of
Austria, one year (1984/85) in Bayreuth.
1987 Habilitation at the Universität Linz.

Research Interests

  • Aharonov-Bohm effect
  • surface effects in superconductors
  • quasiclassical theory of superconductivity
  • structure of vortices (microscopic aspects, local density of states)
  • paramagnetic pair-breaking effects in superconductors
  • foundations of quantum theory

Unpublished notes

A note, written in german, entitled "``..the central mystery of quantum mechanics'' Das Feynmann'sche Doppelspaltexperiment und die Interpretation der Quantenmechanik"


A lecture (pdf file) entitled "Superconducting states in the orbital-paramagnetic pair-breaking regime"

A lecture (pdf file) entitled "Deriving quantum mechanics from statistical assumptions"


I wrote a detailed website (link) on "the statistical interpretation of quantum theory", using the free software tex4ht (details).
The above paper " Is the individuality interpretation of quantum theory wrong ? " (arXiv:1207.6215) gives a summary of this website.

And ...

I wrote a simple script named watchlatex which compiles your latex file automatically every time you save the file. An error will be indicated by an acoustic signal. If no error occurs the xdvi-screen (your viewer's screen) is always up to date.
Here is the linux version, and the audio-script.
