Properties of the quantum vacuum in non-abelian gauge theories
Fernando Ezquerro
In this thesis we analyze the quantum vacuum properties of non-abelian gauge theories. We calculate the energy of the quantum vacuum by non-perturbative methods using Monte Carlo s…
Isospectrality and non-locality of generalized Dirac combs
Giuliano Angelone, Manuel Asorey, Fernando Ezquerro +1
We consider a generalization of Dirac's comb model, describing a non-relativistic particle moving in a periodic array of generalized point interactions. The latter represent the mo…
Matching high and low temperature regimes of massive scalar fields
Manuel Asorey, Fernando Ezquerro
We analyze the matching of high and low temperature expansions of the effective action of massive scalar fields confined between two infinite walls with different boundary conditio…
New vacuum boundary effects of massive field theories
Manuel Asorey, Fernando Ezquerro, Miguel Pardina
Analytical arguments suggest that the Casimir energy in 2+1 dimensions for gauge theories exponentially decays with the distance between the boundaries. The phenomenon has also bee…
Stability of cosmological singularity-free solutions in quadratic gravity
M. Asorey, F. Ezquerro, M. Pardina
We introduce a large family of homogeneous and isotropic cosmological solutions in quadratic gravity which are singularity-free at early and late times. This kind of smooth solutio…
Casimir Energy in (2 + 1)-Dimensional Field Theories
Manuel Asorey, Claudio Iuliano, Fernando Ezquerro
We explore the dependence of vacuum energy on the boundary conditions for massive scalar fields in (2 + 1)-dimensional spacetimes. We consider the simplest geometrical setup given…
Energy preserving boundary conditions in field theory
Manuel Asorey, Fernando Ezquerro
The dynamics of classical field theories is usually governed by field equations, but when fields are constrained to bounded domains it is also dependent on its boundary conditions.…
