Aspects of Quantum Field Theory with Boundary Conditions
Tjoa, Erickson (University of Waterloo, 2019-08-02)This thesis has two modest goals. The primary goal is to deliver three results involving particle detectors interacting with a quantum field in presence of non-trivial boundary conditions (Dirichlet, Neumann, periodic; ... -
The Roles of Causal Propagator in Relativistic Quantum Information
Tjoa, Erickson (University of Waterloo, 2023-05-29)This thesis focuses on the roles of causal propagator — the expectation value of the field commutator — in relativistic quantum information. Consider two observers Alice and Bob, each carrying a two-level quantum system ...
