Reflection positivity in a higher-derivative model with physical bound states of ghosts

Manuel Asorey, Gastão Krein, Miguel Pardina +1

The inclusion of higher derivatives is a necessary condition for a renormalizable or superrenormalizable local theory of quantum gravity. On the other hand, higher derivatives lead…

Gauge and diffeomorphism invariance from quantum information principles

Claudia Núñez, Miguel Pardina, Manuel Asorey +2

Entanglement is a hallmark of quantum theory, yet it alone does not capture the full extent of quantum complexity: some highly entangled states can still be classically simulated.…

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…
