The Casimir energy anomaly for a point interaction
Davide Fermi
The Casimir energy for a massless, neutral scalar field in presence of a point interaction is analyzed using a general zeta-regularization approach developed in earlier works. In a…

The semi-classical limit with delta potentials
Claudio Cacciapuoti, Davide Fermi, Andrea Posilicano
We consider the semi-classical limit of the quantum evolution of Gaussian coherent states whenever the Hamiltonian is given, as sum of quadratic forms, by $\mathsf H= -…

On the necessity of phantom fields for solving the horizon problem in scalar cosmologies
Davide Fermi, Massimo Gengo, Livio Pizzocchero
We discuss the particle horizon problem in the framework of spatially homogeneous and isotropic scalar cosmologies. To this purpose we consider a Friedmann-Lemaitre-Robertson-Walke…
