Termin

Topic 2008/09

Gauge/gravity duality

Through the Anti-deSitter/Conformal Field Theory (AdS/CFT) correspondence of Maldacena and in other conjectured gauge/gravity dualities, the thermodynamics of gauge theories at strong coupling is mapped to the thermodynamics of BHs in 5-dimensional AdS space. The deconfinement transition in quantum chromodynamics is related to the Hawking-Page phase transition on the gravitational side. Matter degrees of freedom are described by additional D-branes embedded in this background geometry, and several quantities of phenomenological interest have been worked out already: shear viscosity, thermalization times, meson spectra, energy loss and jet quenching parameters.

Research Interests and Projects

My research interests comprise theoretical particle physics and its ramifications, in particular quantum field theory, gauge theories, supersymmetry, thermal field theory, and cosmology.

My main current research activities involve

Quantum field theory at finite temperature and density

which is the theoretical tool to analytically study quantum matter under extreme conditions, e.g. ultrarelativistic temperatures and densities that existed in the early universe in the first second after the Big Bang. Of particular interest is the high-temperature regime of quantum chromodynamics which is supposed to describe the quark-gluon plasma that filled the universe during the first 10 μsec's. This form of matter is now believed to be produced fleetingly in "Little Bangs" in ultrarelativistic heavy-ion collider experiments such as RHIC and also expected to exist in the interior of (some) neutron stars.

Nonabelian plasma instabilities

An open problem in quark-gluon plasma physics is to understand the very fast apparent thermalization observed at RHIC and also the extremely low viscosity of the quark-gluon plasma. For both phenomena it has been suggested that nonabelian plasma instabilities may play a crucial role. Together with my former student Paul Romatschke (now at the University of Washington, Seattle) and former post-doc Mike Strickland (now at FIAS, Frankfurt) we were the first group to carry out numerical simulations of nonabelian plasma instabilities in Yang-Mills theories, which are now being studied by several groups in the US and Europe. Recently we have published the first numerical study of nonabelian plasma instabilities in an anisotropically expanding system.

Quantum theory of (supersymmetric) solitons

In recent years, major progress in the understanding of non-perturbative aspects of (supersymmetric) field (and string) theories has been achieved by exploiting dualities in which quantized (supersymmetric) solitons play a central role. Initially it was thought that supersymmetric solitons saturating the so-called BPS bound are protected from quantum corrections, but in collaboration with Peter van Nieuwenhuizen from the State Univ. of New York at Stony Brook, we have found, and are still working out, a number of subtleties and nontrivial results, in particular for 1+1-dimensional supersymmetric kinks (domain walls) and 3+1-dimensional monopoles. Other objects of interest are supersymmetric "confined monopoles" which permit analytical studies with relevance to the outstanding confinement problem of nonabelian gauge theories.

Publications

Since 1984 (the start of my doctoral studies), I have written or co-authored over 100 scientific publications, most of which are available on-line (freely accessible as arXiv.org e-prints) through:

• Hyperlinked list of my publications (HEP-SPIRES database)
  • My TOPCITE publications (papers with more than 50 citations)

This contains the public outreach web pages of the Fachausschuss für Kern- und Teilchenphysik (FAKT) of the ÖPG (Austrian Physical Society), which I was involved in creating and where I am a regular author.

It also hosts now the coordinated efforts of Austrian scientists to appeal for a reversal of the recent decision by the ministry of science to cancel Austria's membership of CERN
