Particle creation in an oscillating spherical cavity
M. R. Setare, A. A. Saharian
We study the creation of massless scalar particles from the quantum vacuum due to the dynamical Casimir effect by spherical shell with oscillating radius. In the case of a small am…
Casimir stress for concentric spheres in de Sitter space
M. R. Setare
The Casimir stress on two concentric spherical shell in de Sitter background for massless scalar field is calculated. The scalar field satisfies Dirichlet boundary conditions on th…
Casimir stress on parallel plates in de Sitter space
M. R. Setare, R. Mansouri
The Casimir stress on two parallel plates in de Sitter background for massless scalar field satisfying Robin boundary conditions on the plates is calculated. The metric is written…
Particle creation by moving spherical shell in the dynamical Casimir effect
M. R. Setare, A. A. Saharian
The creation of massless scalar particles from the quantum vacuum by spherical shell with time varying radius is studied. In the general case of motion the equations are derived fo…
