Gauge Field Localization in the Linear Dilaton Background
K. Farakos, A. Kehagias, G. Koutsoumbas
We study dynamical self-localization of gauge theories in higher dimensions. Specifically, we consider a 5D gauge theory in the linear dilaton (clockwork) background, with a…
The Phase Diagram for the anisotropic SU(2) Adjoint Higgs Model in 5D: Lattice Evidence for Layered Structure
P. Dimopoulos, K. Farakos, G. Koutsoumbas
We explore, by Monte Carlo and Mean Field methods, the five--dimensional SU(2) adjoint Higgs model. We allow for the possibility of different couplings along one direction, describ…
Spatially Anisotropic Four-Dimensional Gauge Interactions, Planar Fermions and Magnetic Catalysis
J. Alexandre, K. Farakos, G. Koutsoumbas +1
We consider magnetic catalysis in a field-theoretic system of (3+1)-dimensional Dirac fermions with anisotropic kinetic term. By placing the system in a strong external magnetic fi…
QED with Dynamical Fermions in an External Magnetic Field
J. Alexandre, K. Farakos, S. J. Hands +2
In this paper, we present results of numerical lattice simulations of two-flavor QED in three space-time dimensions. First, we provide evidence that chiral symmetry is spontaneousl…
Phase Structure of the 5D Abelian Higgs Model with Anisotropic Couplings
P. Dimopoulos, K. Farakos, C. P. Korthals-Altes +2
We establish the phase diagram of the five-dimensional anisotropic Abelian Higgs model by mean field techniques and Monte Carlo simulations. The anisotropy is encoded in the gauge…
Lattice Evidence for Gauge Field Localization on a Brane
P. Dimopoulos, K. Farakos, A. Kehagias +1
We examine the problem of gauge-field localization in higher-dimensional gauge theories. In particular, we study a five-dimensional U(1) by lattice techniques and we find that gaug…
Probing the Gauge Structure of high-temperature superconductors
K. Farakos, G. Koutsoumbas, N. E. Mavromatos
We suggest that a spin-charge separating ansatz, leading to non-Abelian gauge symmetries in doped antiferromagnets, proposed earlier as a way of describing K…
Dynamical Flavour Symmetry Breaking by a Magnetic Field in Lattice QED_3
K. Farakos, G. Koutsoumbas, N. E. Mavromatos
We perform a lattice study, in the quenched approximation, of dynamical mass generation in a system of relativistic (Dirac) fermions, coupled to an Abelian gauge field in (2+1)-dim…
Three-dimensional lattice U(1) gauge-Higgs model at low
P. Dimopoulos, K. Farakos, G. Koutsoumbas
We study the non-compact version of the U(1) gauge-Higgs model in three dimensions for We found that, using this formulation, rather modest lattices approach quite…
Curvature representation of the gonihedric action
G. Koutsoumbas, G. K. Savvidy, K. G. Savvidy
We analyse the curvature representation of the gonihedric action for the cases when the dependence on the dihedral angle is arbitrary.
Quantum Cosmology with Yang-Mills Fields
D. Kapetanakis, G. Koutsoumbas, A. Lukas +1
We examine an extension of the ideas of quantum cosmology and, in particular, the proposal of Hartle and Hawking for the boundary conditions of the Universe, to models which incorp…
