In this article we discuss the invariance under general changes of reference frame of all the physical predictions of particle detector models in quantum field theory in general and, in particular, of those used in quantum optics to model atoms interacting with light. We find explicitly how the light-matter interaction Hamiltonians change under general coordinate transformations, and analyze the subtleties of the Hamiltonians commonly used to describe the light-matter interaction when relativistic motion is taken into account.

I provide an historical account of my contributions to a theory of mind based on quantum physical consideration. In brief, mind appears to be a tachyonic (faster-than-light) and therefore atemporal field embedded throughout spacetime, which came into existence along with matter starting with the big bang and continuing to present day, in what makes up the sought-for Higgs field in particle physics colliders today. Consequently, I offer my speculations, based in quantum physics, on what we may call acausality and its intimate link to mind.
