Condensation of Lee-Yang zeros in scalar field theory
N. G. Antoniou, F. K. Diakonos, X. N. Maintas +1
We show that, at the critical temperature, there is a class of Lee-Yang zeros of the partition function in a general scalar field theory, which location scales with the size of the…
Oscillons and oscillating kinks in the Abelian-Higgs model
C. E. Tsagkarakis, V. Achilleos, F. K. Diakonos +5
We study the classical dynamics of the Abelian Higgs model employing an asymptotic multiscale expansion method, which uses the ratio of the Higgs to the gauge field amplitudes as a…
A non-abelian quasi-particle model for gluon plasma
E. P. Politis, C. E. Tsagkarakis, F. K. Diakonos +2
We propose a quasi-particle model for the thermodynamic description of the gluon plasma which takes into account non-abelian characteristics of the gluonic field. This is accomplis…
Symmetric solitonic excitations of the (1+1)-dimensional Abelian-Higgs "classical vacuum"
F. K. Diakonos, G. C. Katsimiga, X. N. Maintas +1
We study the classical dynamics of the Abelian-Higgs model in (1+1) space-time dimensions bf for the case of strongly broken gauge symmetry. In this limit the wells of the potentia…
Oscillons and oscillating kinks in the Abelian-Higgs model
V. Achilleos, F. K. Diakonos, D. J. Frantzeskakis +5
We study the classical dynamics of the Abelian Higgs model employing an asymptotic multiscale expansion method, which uses the ratio of the Higgs to the gauge field amplitudes as a…
A multi-scale perturbative approach to SU(2)-Higgs classical dynamics: stability of nonlinear plane waves and bounds of the Higgs field mass
V. Achilleos, F. K. Diakonos, D. J. Frantzeskakis +4
We study the classical dynamics of SU(2)-Higgs field theory using multiple scale perturbation theory. In the spontaneously broken phase, assuming small perturbations of the Higgs f…
