Detectors, Reference Frames, and Time
Smith, Alexander R. H. (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 ... -
Quantum reference frames associated with non-compact groups: the case of translations and boosts, and the role of mass
Smith, Alexander R. H.; Piani, Marco; Mann, Robert B. (American Physical Society, 2016-03)Quantum communication without a shared reference frame or the construction of a relational quantum theory requires the notion of a quantum reference frame. We analyze aspects of quantum reference frames associated with ...
