Vortices, Confinement and Higgs fields
Roman Bertle, Manfried Faber
We review lattice evidence for the vortex mechanism of quark confinement and study the influence of charged matter fields on the vortex distribution.
On the ground state of a free massless (pseudo)scalar field in two dimensions
M. Faber, A. N. Ivanov
We investigate the ground state of a free massless (pseudo)scalar field in 1+1-dimensional space-time. We argue that in the quantum field theory of a free massless (pseudo)scalar f…
Bosonic vacuum wave functions from the BCS-type wave function of the ground state of the massless Thirring model
M. Faber, A. N. Ivanov
A BCS-type wave function describes the ground state of the massless Thirring model in the chirally broken phase. The massless Thirring model with fermion fields quantized in the ch…
Electrodynamic Limit in a Model for Charged Solitons
Manfried Faber, Alexander P. Kobushkin
We consider a model of topological solitons where charged particles have finite mass and the electric charge is quantised already at the classical level. In the electrodynamic limi…
Massless Thirring fermion fields in the boson field representation
M. Faber, A. N. Ivanov
We show that the boson field representation of the massless fermion fields, suggested by Morchio, Pierotti and Strocchi in J. Math. Phys. 33, 777 (1992) for the operator solution o…
Quantum field theory of a free massless (pseudo)scalar field in 1+1-dimensional space-time as a test for the massless Thirring model
M. Faber, A. N. Ivanov
We analyse different approaches to the description of the quantum field theory of a free massless (pseudo)scalar field defined in 1+1-dimensional space-time which describes the bos…
