This years FAU^2 workshop is organised by Renata Ferrero, Kristina Giesel and Muxin Han and will take place in ECAP Laboratory from May 20-22, 2025 and aims to explore the interplay between different approaches of quantum gravity at the Planck scale, such as for instance  canonical and covariant loop quantum gravity, group field theory and asymptotically safe gravity, and their corresponding low-energy effective descriptions. We aim to discuss how characteristic properties at the Planck scale might leave an imprint in the effective description of gravitational phenomena at macroscopic scales. Main topics include the application in cosmology and the gravitational collapse, modified gravity and the role of physical (quantum) reference frames in the effective description. By bringing together experts from different areas of quantum gravity, one of the main focuses of the workshop is on comparing different methods for accessing the low-energy sector and analysing possible physical implications of quantum gravity across different scales.
