Filip Reščić and Tomislav Terzić participated in the second Training School of the COST Action CA23130 BridgeQG (Bridging high and low energies in search of quantum gravity), “Quantum and classical gravity in low-energy quantum systems”, held in Belgrade, Serbia, from 22nd to 26th of June 2026. Tomislav Terzić was one of the organisers of the school and is the chief editor of the lecture notes from the BridgeQG schools.

While the first school was dedicated to the high-energy aspects of BridgeQG research, the second school focused on the low-energy side: quantum and classical effects of gravity in low-energy quantum systems. The programme consisted of four main lecture series accompanied by exercises. The lecture notes will be published after the school.
