Non--Commutative Field Theories beyond Perturbation Theory
W. Bietenholz, F. Hofheinz, J. Nishimura
We investigate two models in non-commutative (NC) field theory by means of Monte Carlo simulations. Even if we start from the Euclidean lattice formulation, such simulations are on…
Quantum Liouville theory versus quantized Teichmüller spaces
J. Teschner
This note announces the proof of a conjecture of H. Verlinde, according to which the spaces of Liouville conformal blocks and the Hilbert spaces from the quantization of the Teichm…
Integrable scattering theories with unstable particles
O. A. Castro-Alvaredo, J. Dreissig, A. Fring
We formulate a new bootstrap principle which allows for the construction of particle spectra involving unstable as well as stable particles. We comment on the general Lie algebraic…
Ginzburg - Landau equation from SU(2) gauge field theory
Vladimir Dzhunushaliev, Douglas Singleton
The dual superconductor picture of the QCD vacuum is thought to describe various aspects of the strong interaction including confinement. Ordinary superconductivity is described by…
Kosterlitz-Thouless-like deconfinement mechanism in the 2+1 dimensional Abelian Higgs model
Hagen Kleinert, Flavio S. Nogueira, Asle Sudbo
We point out that the permanent confinement in a compact 2+1-dimensional U(1) Abelian Higgs model is destroyed by matter fields in the fundamental representation. The deconfinement…
Nonperturbative Spontaneous Symmetry Breaking
Vladimir Dzhunushaliev
A nonperturbative approach for spontaneous symmetry breaking is proposed. It is based on some properties of interacting field operators. As the consequences an additional terms lik…
