Radiatively-induced Magnetic moment in four-dimensional anisotropic QED in an external magnetic field
Jean Alexandre, Nick E. Mavromatos
We discuss one-loop radiatively-induced magnetic moment in four-dimensional quantum electrodynamics (QED) with anisotropic coupling, and examine various cases which may be of inter…
Non-Critical Liouville String Escapes Constraints on Generic Models of Quantum Gravity
J. Ellis, N. E. Mavromatos, D. V. Nanopoulos
It has recently been pointed out that generic models of quantum gravity must contend with severe phenomenological constraints imposed by gravitational Cerenkov radiation, neutrino…
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…
Cosmological Evolution in a Type-0 String Theory
G. A. Diamandis, B. C. Georgalas, N. E. Mavromatos +2
We study the cosmological evolution of a type-0 string theory by employing non-criticality, which may be induced by fluctuations of the D3 brane worlds. We check the consistency of…
