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…
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…
Solitons and spontaneous symmetry breaking in 2 and 4 dimensions
Manfried Faber, Joachim Wabnig, Andrei N. Ivanov
We show that mass generation in 1+1 and 3+1 dimensions may occur together with spontaneous symmetry breaking.
Analytical study of low temperature phase of 3D LGT in the plaquette formulation
O. Borisenko, S. Voloshin, M. Faber
We develop an analytical approach for non-abelian gauge models within the plaquette representation where the plaquette matrices play the role of the fundamental degrees of freedom.…
On spontaneous breaking of continuous symmetry in 1+1-dimensional space-time
M. Faber, A. N. Ivanov
We analyse Coleman's theorem asserting the absence Goldstone bosons and spontaneously broken continuous symmetry in the quantum field theory of a free massless (pseudo)scalar field…
