Vacuum energy in the background of delta potentials
M. Scandurra
The response of vacuum to the presence of external conditions is the subject of this work. We consider a generalization of the Casimir effect in the presence of curved boundaries o…

Vacuum energy of a massive scalar field in the presence of a semi-transparent cylinder
Marco Scandurra
We compute the ground state energy of a massive scalar field in the background of a cylindrical shell whose potential is given by a delta function. The zero point energy is express…
