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…

Non-minimal Wu-Yang wormhole
Alexander B. Balakin, Sergey V. Sushkov, Alexei E. Zayats
We discuss exact solutions of three-parameter non-minimal Einstein-Yang-Mills model, which describe the wormholes of a new type. These wormholes are considered to be supported by S…

Completeness principle and quantum field theory on nonglobally hyperbolic spacetimes
Sergey V. Sushkov
We analyse in details the problems which one faces trying to quantize a scalar field on the spacelike cylinder being the simple example of a spacetime with closed timelike curves.…
