Abstract It is well known that a detector, coupled linearly to a quantum field and accelerating through the inertial vacuum with a constant acceleration g , will behave as though it is immersed in a radiation field with temperature T = ( g / 2 π ) . We study a generalization of this result for detectors moving with a time-dependent acceleration g ( τ ) along a given direction. After defining the rate of excitation of the detector appropriately, we evaluate this rate for time-dependent… Expand
Unruh-DeWitt detector event rate for trajectories with time-dependent acceleration

Detecting Acceleration-Enhanced Vacuum Fluctuations with Atoms Inside a Cavity.
This Letter demonstrates that a post-Newtonian rotating atom inside a far-detuned cavity experiences strongly modified quantum fluctuations in the inertial vacuum, and proposes an optomechanical setup that is capable of realizing acceleration-induced particle creation with current technology.

What Do Detectors Detect
By a detector, one has in mind a point particle with internal energy levels, which when set in motion on a generic trajectory can get excited due to its interaction with a quantum field. DetectorsExpand
