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…
Gauss' Law and Non-Linear Plane Waves for Yang-Mills Theory
A. Tsapalis, E. P. Politis, X. N. Maintas +1
We investigate Non-Linear Plane-Wave solutions of the classical Minkowskian Yang-Mills (YM) equations of motion. By imposing a suitable ansatz which solves Gauss' law for the $SU(3…
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…
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…
Static and non-static quantum effects in two-dimensional dilaton gravity
C. Chiou-Lahanas, G. A. Diamandis, B. C. Georgalas +2
We study backreaction effects in two-dimensional dilaton gravity. The backreaction comes from an term which is a part of the one-loop effective action arising from massive sc…
Time-dependent perturbations in two-dimensional String Black Holes
G. A. Diamandis, B. C. Georgalas, X. Maintas +1
We discuss time-dependent perturbations (induced by matter fields) of a black-hole background in tree-level two-dimensional string theory. We analyse the linearized case and show t…
