The Abelian Higgs Model in Three Dimensions with Improved Action

P. Dimopoulos, K. Farakos, G. Koutsoumbas

We study the Abelian Higgs Model using an improved form of the action in the scalar sector. The subleading corrections are carefully analysed and the connection between lattice and…

Unconditional structures of weakly null sequences

S. A. Argyros, I. Gasparis

The following dichotomy is established for a normalized weakly null sequence in a Banach space: Either every subsequence admits a convex block subsequence equivalent to the unit ve…

Mirage Cosmology

A. Kehagias, E. Kiritsis

A brane universe moving in a curved higher dimensional bulk space is considered. The motion induces a cosmological evolution on the universe brane that is indistiguishable from a s…

Density profiles and collective excitations of a trapped two component Fermi vapour

M. Amoruso, I. Meccoli, A. Minguzzi +1

We discuss the ground state and the small-amplitude excitations of a degenerate vapour of fermionic atoms placed in two hyperfine states inside a spherical harmonic trap. An equati…

Even flavor QED3 in an external magnetic field

K. Farakos, G. Koutsoumbas, N. Mavromatos +1

The magnetically induced fermionic condensate is studied at zero and finite temperatures. The effects of a non-homogeneous external magnetic fields is briefly considered.

Unified Models at Intermediate Energy Scales and Kaluza-Klein Excitations

G. K. Leontaris, N. D. Tracas

We discuss the possibility of intermediate gauge coupling unification in unified models of string origin. Useful relations of the β-function coefficients are derived, which ensure…

Astrophysical Probes of the Constancy of the Velocity of Light

J. Ellis, K. Farakos, N. E. Mavromatos +2

We discuss possible tests of the constancy of the velocity of light using distant astrophysical sources such as gamma-ray bursters (GRBs), Active Galactic Nuclei (AGNs) and pulsars…

On magnetic catalysis in even-flavor QED3

K. Farakos, G. Koutsoumbas, N. E. Mavromatos +1

In this paper, we discuss the role of an external magnetic field on the dynamically generated fermion mass in even-flavor QED in three space-time dimensions. Based on some reasonab…

Vacuum structure of gauge theory on lattice with two parallel plaquette action

K. Farakos, G. K. Savvidy

We perform Monte Carlo simulations of a lattice gauge system with an action which contains two parallel plaquettes. The action is defined as a product of gauge group variables over…

On `Graceful Exit' from inflationary phase in two-dimensional Liouville String Cosmology

G. A. Diamandis, B. C. Georgalas, N. E. Mavromatos +1

Within the context of a super-critical (Liouville) string, we discuss (target-space) two-dimensional string cosmology. A numerical analysis indicates that the identification of tim…

String Unification at Intermediate Energies: Phenomenological Viability and Implications

G. K. Leontaris, N. D. Tracas

Motivated by the fact that the string scale can be many orders of magnitude lower than the Planck mass, we investigate the required modifications in the MSSM --functions in orde…

Catalysis of chiral symmetry breaking by external magnetic fields in three-dimensional lattice QED

K. Farakos, G. Koutsoumbas, N. Mavromatos +1

The enhancement of the fermionic condensate due to the presence of both homogeneous and non-homogeneous external magnetic fields is studied for three-dimensional QED.
