Talks

The first part of the talk will briefly discuss the tasks that need to be accomplished in order to formulate such open quantum models in the context of quantum gravity, as well as the challenges involved. As a first step in this direction, a QFT model in the context of linearised gravity is presented, which is formulated in Ashtekar-Barbero variables and then Fock-quantised with a special choice of so-called geometrical clocks as a reference frame. The corresponding master equation and its renormalisation are discussed. Inspired by this QFT model, the second part of the talk presents an application of a quantum mechanical toy model in the context of neutrino oscillations and compares it with existing phenomenological models.
