Slowly rotating scalar field wormholes: the second order approximation
P. E. Kashargin, S. V. Sushkov
We discuss rotating wormholes in general relativity with a scalar field with negative kinetic energy. To solve the problem, we use the assumption about slow rotation. The role of a…

On the vacuum energy of a spherical plasma shell
M. Bordag, N. Khusnutdinov
We consider the vacuum energy of the electromagnetic field interacting with a spherical plasma shell together with a model for the classical motion of the shell. We calculate the h…

Scalar wormholes in cosmological setting and their instability
Sergey V. Sushkov, Yuan-Zhong Zhang
We construct exact nonstatic nonhomogeneous spherically symmetric solutions in the theory of gravity with a scalar field possessing the exponential potential. The solution of parti…
