Gravitational induced decoherence and the role of reference frames: a quantum mechanical toy model — •Ashay Sathe1 and Kristina Giesel2 — 1Friedrich-Alexander-Universität, Erlangen-Nürnberg, Deutschland — 2Friedrich-Alexander-Universität, Erlangen-Nürnberg, Deutschland
In this talk, we investigate a quantum mechanical toy model of gravitationally induced decoherence, with particular emphasis on the role of reference frames in the description of open quantum systems. We analyse two complementary choices of reference frames: a classical reference frame and a quantum reference frame. For each choice, the master equation governing the effective dynamics is derived. We then compare the resulting models and discuss both their common features and their conceptual and dynamical differences.
Keywords: gravitationally induced decoherence; (quantum) reference frames; open quantum systems; linearized gravity
