Zero point energy of a massless scalar field in the cosmic string space-timeWe consider the ground state energy of a massive scalar field in the space-time of a thick cosmic

Self-energy and self-force in the space-time of a thick cosmic string in the background of Gott-Hiscock cosmic string space-time. We find the general expression for the self-energy which

Zero point energy of a massless scalar field in the cosmic string space-timeWe consider the ground state energy of a massive scalar field in the space-time of a thick cosmic

Gauge cosmic chiral strings in general relativityCylindrically symmetric self-gravitating configurations of string (vortex) type are considered

String clouds and radiation flows as sources of gravity in static or rotating cylinders, supported by distributions of cosmic strings stretched in the azimuthal (φ), longitudinal (z) or radial (x

Ground state energy of a massive scalar field in the background of a cosmic string of finite thicknessWe calculate the ground state energy of a massive scalar field in the background of a cosmic string

The vacuum expectation value of the spinor massive field in the cosmic string spacetime Dirac field due to the conical geometry of the cosmic string spacetime. The heat kernel and heat kernel

Self-energy and self-force in the space-time of a thick cosmic string in the background of Gott-Hiscock cosmic string space-time. We find the general expression for the self-energy which

Some remarks on topological defects and their gravitational consequences in the background spacetime of a cosmic string and we discuss the possibility that these shifts could provide a
