What is RQI? Research topics in RQI, Introduction to measuring quantum fields

Measuring quantum fields: What is a particle detector? Deriving the quantum optics light-matter Hamiltonian

Unruh-DeWitt detectors; single-mode and rotating wave appoximations; computing the vacuum excitation probability (switching-function dependence)

Deriving the light-matter interaction Hamiltonian for accelerating detectors

Orginal derivation of Unruh effect; notions of thermality (Gibbs and KMS thermality)

Proving properties of KMS (stationarity and equivalence to Gibbs when Gibbs is well-defined)

Response of a particle detector to stationary states

KMS thermalization of constantly accelerating detector
