Dynamics of the Scalar Condensate in thermal 4D self-interacting Scalar Field Theory on the Lattice
P. Cea, M. Consoli, L. Cosmai
We simulate a four dimensional self-interacting scalar field theory on the lattice at finite temperature. By varying temperature, the system undergoes a phase transition from broke…
Abelian and Center Vortex Condensation in SU(3) Lattice Gauge Theory
Paolo Cea, Leonardo Cosmai
We study the condensation of Abelian and Center vortices in SU(3) lattice gauge theory at finite temperature. We find that both vortices condense in the confined phase of the SU(3)…
External Field Dependence of Deconfinement Temperature in SU(3)
Paolo Cea, Leonardo Cosmai
We study vacuum dynamics of SU(3) lattice gauge theory at finite temperature. Using the lattice Schrödinger functional, SU(3) vacuum is probed by means of an external constant Abel…
Abelian chromomagnetic background field at finite temperature on the lattice
P. Cea, L. Cosmai
The vacuum dynamics of SU(2) and SU(3) lattice gauge theories is studied by means of a gauge-invariant effective action defined using the lattice Schrödinger functional at finite t…
Lattice measurement of the scalar propagator near the symmetry breaking phase transition
P. Cea, M. Consoli, L. Cosmai
Recent lattice simulations of theories in the broken phase show that : a) the shifted field propagator is well reproduced by the simple 2-parameter form ${Z_{\rm prop}\o…
Lattice measurement of the energy-gap in a spontaneously broken phase
P. Cea, M. Consoli, L. Cosmai
Using lattice simulations of a one-component theory, we have measured the energy spectrum in the broken phase at various lattice sizes. Our data show t…
