Teoría cuántica de campos escalares masivos en el espacio-tiempo de una cuerda negra.

Quantum field theory in curved black string space-time is constructed considering the specific case of massive scalar field. The renormalized vacuum expectation value of the stress tensor of the scalar field is presented and discussed. It is shown that a violation of the weak energy condition of Gen...

Summary:Quantum field theory in curved black string space-time is constructed considering the specific case of massive scalar field. The renormalized vacuum expectation value of the stress tensor of the scalar field is presented and discussed. It is shown that a violation of the weak energy condition of General Relativity occurs at the horizon of the black string.
Se ofrece una formulación para la teoría cuántica de campos en un espacio-tiempo curvado correspondiente a una cuerda cósmica negra, especificándose los resultados para campos escalares masivos. Se presentan y discuten las expresiones obtenidas para el valor esperado de vacío renormalizado del tensor de energía-momentum del campo escalar, y se demuestra que la condición débil de energía de la Relatividad General se viola en el horizonte de la cuerda.
