Dynamical Symmetry Breaking in Planar QED
P. Cea, L. Tedesco
We investigate (2+1)-dimensional QED coupled with Dirac fermions both at zero and finite temperature. We discuss in details two-components (P-odd) and four-components (P-even) ferm…
Dynamical Generation of the Primordial Magnetic Field by Ferromagnetic Domain Walls
Paolo Cea, Luigi Tedesco
The spontaneous generation of uniform magnetic condensate in gives rise to ferromagnetic domain walls at the electroweak phase transition. These ferromagnetic domain walls…
Spontaneous Generation of Magnetic Field in Three Dimensional QED at Finite Temperature
Paolo Cea, Luigi Tedesco
We investigate the effects of thermal fluctuations on the spontaneous magnetic condensate in three dimensional QED coupled with P-odd Dirac fermions. Our results show that the phen…
Perturbation Theory with a Variational Basis: the Generalized Gaussian Effective Potential
Paolo Cea, Luigi Tedesco
The perturbation theory with a variational basis is constructed and analyzed.The generalized Gaussian effective potential is introduced and evaluated up to the second order for sel…
Vacuum Stability for Dirac Fermions in Three Dimensions
Paolo Cea
I investigate three dimensional abelian and non-abelian gauge theories interacting with Dirac fermions. Using a variational method I evaluate the vacuum energy density in the one-l…
Lattice effective potential of : nature of the phase transition and bounds on the Higgs mass
P. Cea, L. Cosmai, M. Consoli +1
We present a detailed discussion of Spontaneous Symmetry Breaking (SSB) in . In the usual approach, inspired by perturbation theory, one predicts a second-order phase tra…
