Reconsidering the Vacuum Energy of a Massive Scalar Field in a Spherical Cavity
M. Bordag, I. G. Pirozhenko
We reconsider the vacuum (Casimir) energy of a massive scalar field obeying Dirichlet boundary conditions inside a spherical cavity. Using zeta-function regularization, we carefull…
Casimir effect for scalar field rotating on a disk
M. Bordag, I. G. Pirozhenko
We compute the vacuum energy of a scalar field rotating with angular velocity on a disk of radius and with Dirichlet boundary conditions. The rotation is introduced by a me…
Casimir effect with an unstable mode
M. Bordag, I. G. Pirozhenko
We consider the Casimir effect in a (1+1)-dimensional model with a critical mode. Such a mode gives rise to a condensate described by the nonlinear Gross-Pitaevskii equation. In th…
Perturbations of classical fields by gravitational shockwaves
D. V. Fursaev, E. A. Davydov, I. G. Pirozhenko +1
Gravitational shockwaves are geometries where components of the transverse curvature have abrupt behaviour across null hypersurfaces, which are fronts of the waves. We develop a ge…
Electrodynamics under Action of Null Cosmic Strings
D. V. Fursaev, I. G. Pirozhenko
A method to study electromagnetic (EM) effects generated by a straight null cosmic string moving in classical EM fields is suggested. The string is shown to induce an additional EM…
The closed piecewise uniform string revisited
M. Bordag, I. G. Pirozhenko
We reconsider the composite string model introduced {30 years ago} to study the vacuum energy. The model consists of a scalar field, describing the transversal vibrations of a stri…
