Detectors, Reference Frames, and Time
(University of Waterloo, 2017-11-08)This thesis is divided into three parts. Part I investigates the behaviour of Unruh-DeWitt detectors on curved spacetimes admitting a Wightman function and the associated measurement model is identified. These detectors ... -
The Effects of Uniform Acceleration on the Correlation Harvesting
(University of Waterloo, 2023-09-22)Quantum field theory (QFT) in curved spacetime focuses on the analysis of quantum fields—representing fundamental particles and their interactions—within a curved spacetime geometry, accounting for relativistic effects. Among ... -
Exact Results in Supersymmetric Gauge Theory
(University of Waterloo, 2016-08-30)Exact results are a key component for understanding any physical theory. Unfortunately in the context of quantum field theory (QFT) they are in general impossible to obtain, and we need some sort of approximations. However ... -
The Unruh-DeWitt Detector Model: Modified Dispersion and Nonlinear Couplings
(University of Waterloo, 2021-09-30)In this work, we employ the Unruh-DeWitt (UDW) detector model to various ends. We present applications of this relativistic detector model to quantum optics, including decoherence in optical cavities and non-linear quantum ...
