Quantum Effects on Tachyon Dynamics
arXiv:0805.3563 · doi:10.1088/1126-6708/2008/08/051
Abstract
We investigate the relevance of quantum effects in the study of bulk tachyon dynamics. We analyze the behavior of a system which consists of a tachyon, the graviton and the dilaton through the use of the Wheeler-DeWitt equation in the mini-superspace approximation, The singular behavior of the classical solution for the system is modified so that the quantum behavior seems to be regular.
