Zitterbewegung in the AdS Cosmic String Space-Time

Аннотация

We consider the Zitterbewegung (ZB) effect induced in the AdS (anti-de Sitter) space-time by a cosmic string. Near the cosmic string, the effects of curvature play a dominant role. The ZB was calculated based on the Dirac equation in a curved space-time. An expression for a current is obtained. Its evolution and dependence on the distance from the event horizon are analyzed.
