Central topics will include the notions of observers and causality\, but the scope extends to related ideas such as measurements\, quantum reference frames\, quantum groups\, and more. \nWe will address questions such as:\n– What structures are required to define observers in quantum gravity?\n– What is the relation among the notions of observers\, observables\, and measurements?\n– Which features of causal structure are genuinely new in quantum gravity compared to classical spacetime?\n– Which other fundamental concepts should be examined to help build a shared conceptual language? \nConfirmed invited speakers: \nCharis Anastopoulos (U. of Patras)\nČaslav Brukner (IQOQI Vienna)\nEsteban Castro-Ruiz (IQOQI Vienna)\nKristina Giesel (Erlangen – Nuremberg U.)\nGiulia Gubitosi (U.

Understanding the physics of the source is crucial\, since currently this is the main source of uncertainty in tests of quantum-gravity induced propagation anomalies. This workshop will be crucial in involving astrophysicists not working on quantum gravity who are however expert in source modelling.

Verlinde and K. Zurek proposed that if area fluctuations in quantum gravity scale proportionally with the area itself\, then their effects could\, in principle\, be detected using currently available technologies. This idea resonates with a longstanding insight\, dating back to Einstein\, that (quantum) fluctuations can encode crucial and potentially observable information about otherwise inaccessible microscopic properties. In this talk\, I will first discuss the phenomenological implications of the Verlinde–Zurek relation. I will then argue that\, from a theoretical standpoint\, this relation lies at the very heart of quantum gravity. Finally\, I will address the central question: What is the entity that fluctuates\, and what are its physical properties? \nZoom link sent by email URL:https://web.infn.it/BridgeQG/event/wg5-online-meeting/ END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Rome:20251014T160000 DTEND;TZID=Europe/Rome:20251014T170000 DTSTAMP:20260511T062013 CREATED:20250911T100224Z LAST-MODIFIED:20250911T100224Z UID:1516-1760457600-1760461200@web.infn.it SUMMARY:WG1 Online Meeting DESCRIPTION:The regular WG1 meetings restart after the summer.

Elles sont incompatibles lorsqu’elles sont appliquées à l’Univers primitif ou aux trous noirs\, où la gravité et les effets quantiques sont tous deux importants.\nLa gravité quantique est une tentative d’unifier les deux théories\, qui permettrait notamment de comprendre les phénomènes impliquant de grandes quantités de matière ou d’énergie sur de petites dimensions spatiales\, tels que les trous noirs ou l’origine de l’Univers.\nLa mécanique quantique et la relativité générale sont très bien vérifiées et jusqu’à présent aucune expérience ne les contredit. Dans cette conférence on présentera les concepts de base des deux théories ainsi que de la gravité quantique. Des expériences possibles pour la detection de la gravité quantique seront aussi discutées.
