It is known that the vortex gravitational field in rotating cylindrically symmetric configurations leads to an exotic contribution in the total effective stress-energy tensor, which is favorable for the formation of cylindrical wormhole throats. This leads to an opportunity to obtain wormholes without exotic matter, and there are examples of such exact wormhole solutions (including vacuum ones...

We construct explicit examples of globally regular static, spherically
symmetric solutions in general relativity with scalar and electromagnetic
fields, describing (1) traversable wormholes with flat and AdS asymptotics
and (2) regular black holes, in particular, black universes. (A black universe
is a regular black hole with...

We demonstrate that non-zero mass difference between electron and positron that breaks CPT-symmetry produces also an electric charge non-conservation and non-zero photon mass.Cosmological bounds on
non-zero photon mass can be transformed into bounds on electron-positron mass difference that 10-15 order of magnitude stronger than existing direct bounds

The $U_L(2)\bigotimes U_R(2) $ gauge model for the unified theory
of the electromagnetic and weak interactions which is free from
the auxiliary self-interaction scalar field is developed. Due to
breaking the initial symmetry, the $SU_L(2)\bigotimes U_R(1) $
Lagrangian is derived. The obtained $SU_L(2)\bigotimes U_R(1) $
Lagrangian contains all the terms corresponding to the free...

Fermions are considered in a multidimensional space with two extra dimensions. Fermion Lagrangian contains coupling to a metric of deformed extra space. We show that the point-like defect on a space with topology of sphere leads to fermion interaction with such defect and calculate cross section of a fermion scattering on such defect.
