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…
