dc.description.abstractWe consider a pointlike two-level system undergoing uniformly accelerated motion. We evaluate the transition probability rate of this system coupled to a massless scalar field near a fluctuating event horizon. Such horizon fluctuations are generated using random noise. We study the case of centered, stationary and Gaussian random processes. The transition probability of the two-level system is obtained from the positive-frequency Wightman function calculated to one-loop order in the noise averaging process. Our results show how this fluctuating-horizon model modifies the response function of the two-level system.
