Conclusions • We looked at the effects of spatial profiles for Unruh-DeWitt detectors • Interaction Hamiltonians can be constructed such that the field is peaked around some desired frequency • The transition rates of these detectors can have a thermal signature but with an oscillatory contribution Antony Richard Lee RQI 2012 – Perimeter Institute Unruh Mode Detectors
Future Work • Extensions to different fields • Consider different couplings • Cavities Antony Richard Lee RQI 2012 – Perimeter Institute Unruh Mode Detectors
