New universality class of chiral symmetry breaking in the strongly coupled U(1) model
W. Franzki, J. Jersak
We describe a 4D U(1) lattice gauge theory with charged scalar and fermion matter fields ( model). At sufficiently strong gauge coupling, the chiral symmetry is broke…
Strongly coupled lattice gauge theory with dynamical fermion mass generation in three dimensions
I. M. Barbour, N. Psycharis, E. Focht +2
We investigate the critical behaviour of a three-dimensional lattice $\chiUϕ_3$ model in the chiral limit. The model consists of a staggered fermion field, a U(1) gauge field (with…
Dynamical fermion mass generation at a tricritical point in strongly coupled U(1) lattice gauge theory
W. Franzki, J. Jersak
Fermion mass generation in the strongly coupled U(1) lattice gauge theory with fermion and scalar fields of equal charge is investigated by means of numerical simulation with dynam…
Strongly coupled U(1) lattice gauge theory as a microscopic model of Yukawa theory
W. Franzki, J. Jersak
Dynamical chiral symmetry breaking in a strongly coupled U(1) lattice gauge model with charged fermions and scalar is investigated by numerical simulation. Several composite neutra…
Scaling of gauge balls and static potential in the confinement phase of the pure U(1) lattice gauge theory
J. Cox, W. Franzki, J. Jersak +4
We investigate the scaling behaviour of gauge-ball masses and static potential in the pure U(1) lattice gauge theory on toroidal lattices. An extended gauge field action $-\sum_P(β…

J. Cox, W. Franzki, J. Jersák +2
We explore the compact U(1) lattice gauge theory with staggered fermions and gauge field action -\sum_P [β\cos(Θ_P) + γ\cos(2Θ_P)], both for dynamical fermions and in the quenched…
Properties of the non-Gaussian fixed point in 4D compact U(1) lattice gauge theory
J. Cox, W. Franzki, J. Jersak +3
We examine selected properties of the gauge-ball spectrum and fermionic variables in the vicinity of the recently discussed non-Gaussian fixed point of 4D compact U(1) lattice gaug…
Non-Gaussian fixed point candidates in the 4D compact U(1) gauge theories
W. Franzki, J. Jersak, C. B. Lang +1
Some interesting nonperturbative properties of the strongly coupled 4D compact U(1) lattice gauge theories, both without and with matter fields, are pointed out. We demonstrate tha…
Scaling behavior at the tricritical point in the fermion-gauge-scalar model
W. Franzki
We investigate a strongly coupled U(1) gauge theory with fermions and scalars on the lattice and analyze whether the continuum limit might be a renormalizable theory with dynamical…
Gauge invariant generalization of the 2D chiral Gross-Neveu model
W. Franzki, J. Jersák, R. Welters
By means of the Lee-Shrock transformation we generalize the 2D Gross-Neveu (GN) model to a U(1) gauge theory with charged fermion and scalar fields in 2D ( model). The…
Tricritical point in strongly coupled U(1) gauge theory with fermions and scalars
W. Franzki, J. Jersák
We investigate the tricritical point in the lattice fermion--gauge--scalar model with U(1) gauge symmetry. In the vicinity of this point, in the phase with the broken chiral symmet…
Chiral phase transition in a lattice fermion--gauge--scalar model with U(1) gauge symmetry

The chiral phase transition induced by a charged scalar field is investigated numerically in a lattice fermion-gauge-scalar model with U(1) gauge symmetry, proposed recently as a m…

We report the recent results from the computer simulations of a fermion-gauge-scalar model with dynamical chiral-symmetry breaking and chiral transition induced by the scalar field…
Spectrum and scaling in a strongly coupled fermion-gauge-scalar model
Wolfgang Franzki, Xiang-Qian Luo
The strongly coupled lattice gauge models show an interesting mechanism of dynamical mass generation. If a suitable continuum limit can be found, one may think of it as an alternat…
On the equivalence between 2D Yukawa and Gross-Neveu models
E. Focht, W. Franzki, J. Jersak +1
We study numerically on the lattice the 2D Yukawa model with the U(1) chiral symmetry and = 16 at infinite scalar field self-coupling. The scaling behaviour of the fermion ma…
Study of the Asymptotic Freedom of 2D Yukawa Models on the Lattice
A. K. De, E. Focht, W. Franzki +2
We investigate on the lattice the Yukawa models in 2 dimensions with Z(2) and U(1) symmetries. These models reduce to the usual and chiral Gross-Neveu models, respectively, when th…
How much are 2d Yukawa models similar to the Gross-Neveu models?
A. K. De, E. Focht, W. Franzki +1
We present numerical evidence that the 2d Yukawa models with strong quartic selfcoupling of the scalar field have the same phase structure and are asymptotically free in the Yukawa…
