The goal of this physics school is to offer master and Ph.D. students from the field of experimental and theoretical physics as well as mathematics and philosophy a coherent introduction to the subject of quantum gravity in low energy quantum systems from both theoretical and experimental perspectives.

The participants will receive training in the theoretical description of quantum system under the influence of gravity and how to predict observable signatures. They will learn how specific experimental setups can be used to test the theoretical predictions. This education equips the participants with the skills to bridge the gap between theory and experiment in the field of the interplay between quantum systems and classical and quantum gravity research in the future.

This is the second of a series of Training Schools organised by the European COST Action CA23130 – BridgeQG: Bridging high and low energies in search of quantum gravity.
While the focus of the first training school was on the high-energy aspects of the BridgeQG research topics, the focus of this training school will be on the low-energy aspects.
A third school will cover the combination of the two branches.

The school consists of four main lectures, which are accompanied by tutorial classes. In addition there will be an introductory short lecture on quantum gravity phenomenology, and a concluding short lecture. Lecture notes will be published after the school.

Lecturers and topics (Final titles of the lectures will be announced soon)
