چکیده

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 of the massless Thirring model, agrees completely with the existence of the chirally broken phase in the massless Thirring model revealed in EPJC 20, 723 (2001) and hep–th/0112183, when the free massless boson fields are described by the quantum field theory, free of infrared divergences in 1+1–dimensional space–time, formulated in hep–th/0112184 and hep–th/0204237.

No massless boson in chiral symmetry breaking in NJL and Thirring models

We show that the chiral symmetry breaking occurs in the vacuum of the massless Nambu-Jona-Lasinio (NJL) and Thirring models without a Goldstone boson. The basic reason of non-existence of the massless boson is due to the fact that the new vacuum after the symmetry breaking acquires nonzero fermion mass which inevitably leads to massive bosons. The new vacuum has a finite condensate of 〈ψ̄ψ〉 with...

Bosonization of massless free fermion fields We are going to write an explicit expression for a massless free fermion field as a non-local function of a free massless pseudo-scalar

The kinematical constraints on field theories in two space-time dimensions lead to many unusual effects which have no analogue in higher dimensions. Perhaps the strangest of these is the equivalence between large classes of Bose and Fermi field theories. This correspondence, which has been dubbed bosonization, provides a transparent unified method for solving two dimensional Fermi theories [ l*...

Bosons after Symmetry Breaking in Quantum Field Theory

We present a unified description of the spontaneous symmetry breaking and its associated bosons in fermion field theory. There is no Goldstone boson in the fermion field theory models of Nambu-Jona-Lasinio, Thirring and QCD2 after the chiral symmetry is spontaneously broken in the new vacuum. The defect of the Goldstone theorem is clarified, and the ”massless boson” predicted by the theorem is ...

On unrenormalizability of the massless Thirring model

We discuss the renormalizability of the massless Thirring model in terms of the causal fermion Green functions and correlation functions of left—right fermion densities. We obtain the most general solution of the massless Thirring model with dynamical dimensions of fermion fields, parameterized by two arbitrary parameters. We show that in the massless Thirring model there are no solutions which...

Bosonic vacuum wave functions from the BCS–type wave function of the ground state of the massless Thirring model

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 chirally broken phase bosonizes to the quantum field theory of the free massless (pseudo)scalar field (Eur. Phys. J. C 20, 723 (2001)). The wave functions of the ground state of the free massless (pseudo)scalar field ar...
