Quasi-normal modes of a dielectric ball and some their implications
V. V. Nesterenko, A. Feoli, G. Lambiase +1
It is shown that the quasi-normal modes arise, in a natural way, when considering the oscillations in unbounded regions by imposing the radiation condition at spatial infinity with…
Calculation of the Casimir energy at zero and finite temperature: Some recent results
V. V. Nesterenko, G. Lambiase, G. Scarpetta
This survey summarizes briefly results obtained recently in the Casimir energy studies devoted to the following subjects: i) account of the material characteristics of the media in…
Casimir effect for a perfectly conducting wedge in terms of local zeta function
V. V. Nesterenko, G. Lambiase, G. Scarpetta
The vacuum energy density of electromagnetic field inside a perfectly conducting wedge is calculated by making use of the local zeta function technique. This regularization complet…
Casimir effect for a dilute dielectric ball at finite temperature
V. V. Nesterenko, G. Lambiase, G. Scarpetta
The Casimir effect at finite temperature is investigated for a dilute dielectric ball; i.e., the relevant internal and free energies are calculated. The starting point in this stud…
Casimir Energy of a Semi-Circular Infinite Cylinder
V. V. Nesterenko, G. Lambiase, G. Scarpetta
The Casimir energy of a semi-circular cylindrical shell is calculated by making use of the zeta function technique. This shell is obtained by crossing an infinite circular cylindri…
Casimir energy of a dilute dielectric ball in the mode summation method
G. Lambiase, G. Scarpetta, V. V. Nesterenko
In the --approximation the Casimir energy of a dilute dielectric ball is derived using a simple and clear method of the mode summation. The addition theorem for the Be…
