Magnetic field production after inflation
Andres Diaz-Gil, J. Garcia-Bellido, M. Garcia Perez +1
We study the electromagnetic field production during preheating after hybrid inflation in a model with the field content of the Standard Model, coupled to a singlet inflaton. We fi…
Fermions on tori in uniform abelian fields
L. Giusti, A. Gonzalez-Arroyo, Ch. Hoelbling +2
We study Fermi fields defined on tori in the presence of gauge backgrounds carrying non-trivial topology. We show that 2k dimensional field space can alternatively be described by…
Large N corrections to the strong coupling behaviour of SU(N)/Z_N lattice gauge theories
A. Gonzalez-Arroyo, C. Pena
We derive a formula for the large N behaviour of the expectation values of an arbitrary product of Wilson loops in the adjoint representation. We show the consequences of our formu…
Weyl-Dirac zero-mode for calorons
M. Garcia Perez, A. Gonzalez-Arroyo, C. Pena +1
We give the analytic result for the fermion zero-mode of the SU(2) calorons with non-trivial holonomy. It is shown that the zero-mode is supported on ONLY ONE of the constituent mo…
Combinatorics of lattice paths with and without spikes
A. Gonzalez-Arroyo
We derive a series of results on random walks on a d-dimensional hypercubic lattice (lattice paths). We introduce the notions of terse and simple paths corresponding to the path ha…
Gauge invariant investigation of the nature of Confinement
A. Gonzalez-Arroyo, A. Montero
We observe a strong correlation between the decrease in the number of action density peaks in SU(2) Yang-Mills configurations with cooling and that of the string tension. The natur…
