On the solution of the massless Thirring model with fermion fields quantized in the chiral symmetric phase
M. Faber, A. N. Ivanov
Correlation functions of fermionic fields described by the massless Thirring model are analysed within the operator formalism developed by Klaiber and the path-integral approach wi…
On free massless (pseudo)scalar quantum field theory in 1+1-dimensional space-time
M. Faber, A. N. Ivanov
We construct a consistent quantum field theory of a free massless (pseudo)scalar field in 1+1-dimensional space-times free of infrared divergences. We show that a continuous symmet…
Vortices in the SU(2)-Higgs model -- Vortices and the covariant adjoint Laplacian
Roman Bertle, Manfried Faber, Albert Hirtl
Vortices in the SU(2)--Higgs model: The presence of a fundamental Higgs in the SU(N)-Higgs model yields color screening at some finite distance. Whereas the transition to the Higgs…
Susceptibility of Monte-Carlo Generated Projected Vortices
Roman Bertle, Michael Engelhardt, Manfried Faber
We determine the topological susceptibility from center projected vortices and demonstrate that the topological properties of the SU(2) Yang-Mills vacuum can be extracted from the…
Direct Laplacian Center Gauge
M. Faber, J. Greensite, S. Olejnik
We introduce a variation of direct maximal center gauge fixing: the ``direct Laplacian'' center gauge. The new procedure overcomes certain shortcomings of maximal center gauge, ass…
On the equivalence between sine-Gordon model and Thirring model in the chirally broken phase of the Thirring model
M. Faber, A. N. Ivanov
We investigate the equivalence between Thirring model and sine-Gordon model in the chirally broken phase of the Thirring model. This is unlike all other available approaches where…
