Fancy picture, eh?
It's from an article

ByGeorge about my work
(well, sort of...).

Research Topics

Both a short (version 2006) and more detailled description (version 2005) of progress and perspectives of my research interests as .pdf files. The latter (part of my Habilitation thesis) contains 8 pages of general introduction and 30 pages summarising my research so far in some more detail. Research perspectives are best covered in the short version. A talk I recently gave on my research (pdf, 2005), and a list of Invited Conference Contributions, Seminars and Lectures (.pdf file, version 2006).

Series of 3 lectures on Effective Field Theories in Few-Nucleon Systems, National Nuclear Physics Summer School June 2008 (.djvu format, manuscript).

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 what else?? I don't know yet...

Or those dudes who hired me from 1997 to 1999??
Or the blighters who payed the bills between 1999 and 2005??
