Emergent relativistic-like Kinematics and Dynamical Mass Generation for a Lifshitz-type Yukawa model
J. Alexandre, N. E. Mavromatos, D. Yawitch
We study the Infra Red (IR) limit of dispersion relations for scalar and fermion fields in a Lifshitz-type Yukawa model, after dressing by quantum fluctuations. Relativistic-like d…
Liouville-Lifshitz theory in 3+1 dimensions
J. Alexandre, K. Farakos, A. Tsapalis
We consider a four-dimensional theory in the z=3 Lifshitz context, with an exponential (Liouville) potential. We determine the exact renormalized potential of the theory and derive…
Neutrino oscillations in a Robertson-Walker Universe with space time foam
J. Alexandre, K. Farakos, N. E. Mavromatos +1
In Phys. Rev. D77 (2008) 105001, we have studied decoherence models for flavour oscillations in four-dimensional stochastically fluctuating space times and discussed briefly the se…
Non-renormalization for the Liouville wave function
J. Alexandre, Anna Kostouki, N. E. Mavromatos
Using an exact functional method, within the framework of the gradient expansion for the Liouville effective action, we show that the kinetic term for the Liouville field is not re…
Neutrino oscillations in a stochastic model for space-time foam
J. Alexandre, K. Farakos, N. E. Mavromatos +1
We study decoherence models for flavour oscillations in four-dimensional stochastically fluctuating space times and discuss briefly the sensitivity of current neutrino experiments…
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…
QED in a Strong External Magnetic Field: Beyond the Constant Mass Approximation
J. Alexandre, K. Farakos, G. Koutsoumbas
We solve the Schwinger-Dyson equations for QED in 2+1 or 3+1 dimensions in the presence of a strong homogeneous external magnetic field. The magnetic field is assumed strong enough…
