Research Topics

Effective Field Theories (EFT) of Non-Relativistic Systems

• Compton scattering and nucleon polarisabilities in Effective Nuclear Theory, an extension of Chiral Perturbation Theory to include nucleons. See here for a recent proceeding (version 2004) summarising this part.
  
• Two, three and many nucleon systems at very low energies in Effective Nuclear Theory. Especially: Deuteron, Triton and Helium-3 probed with electromagnetic and weak currents. Click here for the .gzip'ed version of a notebook calculating nd-scattering and the triton system in Effective Field Theory without pions (Mathematica, 3MBytes due to fancy pictures, version 2005).
• Nucleons and nuclei in small boxes in Effective Nuclear Theory, also relevant to lattice extractions.
• Nuclear Matter with EFT.
  
• Non-relativistic QCD: The EFT of QCD in systems of two or more heavy quarks. Especially: Conceptual problems (classification of different regimes, beta function, renormalisation properties). Since the underlying theory, QCD, is known, this helps one understand any EFT of non-relativistic systems. How to calculate scattering amplitudes in systems of heavy quarks using a non-relativistic prescription.

  Non-perturbative Physics of QCD

• Instantons, theta vacua, U_A(1) problem
• Dual Meißner Effect ('t Hooft-Mandelstam Mechanism) for Confinement in Abelian Projections in the continuum.
• Non-perturbative gauge fixing in the Hamiltonian and Lagrangean Formulation of QCD.

And that was the official part...

• Ever visited the absolutely weird guys I worked with between 1991 and 1997??
• Or those dudes who hired me from 1997 to 1999?? 
• Or the blighters who payed the bills between 1999 and 2005??
• Ever wondered what modern translation computers can do for you? Check out what they did to abstract, introduction and summary of one of my papers!
• Annals of Improbable Research homepage
• Urban Legends: The modern myths of everyday life
• And most important: How full is the Coffee Machine --- in Cambridge.
• The life of a future student of the illustrous New York University, and lots of more good stuff.
• "I can eat glass" in a few hundred languages.
• And what if you found the solution to all Physics problems? Don't contact me!
  
• In case you wondered where it all ends: The last page of the internet can be found here... (Cached because it disappeared. Strange.)
