We investigate the radiation emitted by a uniformly moving charged scalar particle in the spacetime of a point-like global monopole. We calculate the total energy radiated by the particle and the corresponding spectrum for ...

© 2016 American Physical Society.We find analytic asymptotic expressions at low temperature for the Casimir free energy, entropy, and pressure of two parallel graphene sheets in the framework of the Lifshitz theory. The ...

We consider the self-energy and the self-force for scalar massless particles at rest in the short-throat flat-spacetime wormhole background. In some limiting cases we found how the sign of the self-energy changes with the ...

We consider the self-energy and the self-force for scalar massive and massless particles at rest in a class of wormhole spacetimes. We develop a general approach to obtain the self-force and apply it to the two specific ...

We find the contribution to the vacuum expectation value of the energy-momentum tensor of a massive Dirac field due to the conical geometry of the cosmic string spacetime. The heat kernel and heat kernel expansion for the ...

The vacuum average value of the stress-energy tensor of a massive scalar field with nonminimal coupling ξ to the curvature on the short-throat flat-space wormhole background is calculated. The final analysis is made ...
