On the thin wall limit of thick planar domain walls
S. Ghassemi, S. Khakshournia, R. Mansouri
Considering a planar gravitating thick domain wall of the theory, we demonstrate how the Darmois junction conditions written on the boundaries of the thick wall with the emb…
Dynamics of a Spherical Null Shell within the Distributional Formalism
Samad Khakshournia, Reza Mansouri
Dynamics of a null thin shell immersed in a generic spherically symmetric spacetime is obtained within the distributional formalism. It has been shown that the distributional forma…
Dynamics of general relativistic spherically symmetric dust thick shells
Samad Khakshournia, Reza Mansouri
We consider a spherical thick shell immersed in two different spherically symmetric space-times. Using the fact that the boundaries of the thick shell with two embedding space-time…
Casimir energy for self-interacting scalar field in a spherical shell
M. R. Setare, R. Mansouri
In this paper we calculate the Casimir energy for spherical shell with massless self-interacting scalar filed which satisfying Dirichlet boundary conditions on the shell. Using zet…
Junction equations for two spherically symmetric spacetimes and the distributional method
S. Khakshournia, R. Mansouri
Applying the distributional formalism to study the dynamics of thin shells in general relativity, we regain the junction equations for matching of two spherically symmetric spaceti…
Signature Change, Inflation, and the Cosmological Constant
Reza Mansouri, Kourosh Nozari
Colombeau's generalized functions are used to adapt the distributional approach to singular hypersurfaces in general relativity with signature change. Equations governing the dynam…
