On the renormalization of the sine-Gordon model
H. Bozkaya, M. Faber, A. N. Ivanov +1
We analyse the renormalizability of the sine-Gordon model by the example of the two-point Green function up to second order in alpha_r(M), the dimensional coupling constant defined…
On the vacua in the massless Thirring model
M. Faber, A. N. Ivanov
We calculate the most general effective potential for the massless Thirring model in dependence of the local fields of all fermion-antifermion collective excitations. We analyse th…
Dynamical breaking of conformal symmetry in the massless Thirring model
M. Faber, A. N. Ivanov
We discuss conformal invariance of the massless Thirring model. We show that conformal symmetry of the massless Thirring model is dynamically broken due to the constant of motion c…
Goldstone bosons in the massless Thirring model. Witten's criterion
M. Faber, A. N. Ivanov
We discuss the Ward identity and the low-energy theorem for the divergence of the axial-vector current in the massless Thirring model with fermion fields quantized in the chirally…
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…
