It states that while an inertial observer might fre eze in the Minkowski vacuum\, an accelerated observer might find themselve s burning up in the same quantum state. Not only does this effect challeng e our usual notion of the “particle” as a central object in fundamental ph ysics\, but it also points toward the possibility of deeper connections be tween quantum theory\, thermodynamics\, and spacetime.\n\n2026 marks the f iftieth anniversary of Unruh’s seminal paper on acceleration-induced therm ality. Over the last five decades\, many developments have advanced the un derstanding of thermality in quantum field theory in curved spacetimes. It is thus with great joy that we join this August to celebrate fifty years of achievements.\n\nIn a bold attempt to address fifty years of progress i n five days\, we will discuss topics including the Fulling–Davies–Unruh ef fect and related predictions\, entropy and entanglement in QFT\, applicati ons of Tomita–Takesaki modular theory\, experimental prospects for measuri ng thermality\, and much more.

The conference is immediately followed by a 1 day meeting of the Algebraic Qua ntum Field Theory UK network which may be of interest to many participants .\nAlgebraic QFT places strong emphasis on algebras of local observables. Its clear conceptual and technical framework has led to important progress \, such as the rigorous perturbative construction of quantized gauge theor ies. It forms the foundation of local measurement theory\, providing novel insights into locality and causality in relativistic quantum information\ , and its operator algebraic techniques have been a recent focus in quantu m gravity research. However\, various relevant observables of interest for a quantum field are not well-localised. Examples include 'dressed'\, rela tional or asymptotic/boundary observables in QED\, more general Yang-Mills theories and quantum gravitation. We are therefore challenged with incorp orating these semi-local observables into a rigorous framework for quantum field theory and establish their operator algebraic structure\, as well a s addressing operational questions such as to what extent these observable s can be measured.\nThe past few years have seen numerous developments inv olving semi-local features of quantum fields and the challenges that they present. This conference provides an opportunity to present and discuss th ese developments and set the agenda on semi-local quantum physics for the upcoming years. We invite all researchers working on or interested in thes e topics to attend and apply to present their work.\n\nConfirmed speakers include\nJeremy Butterfield (Cambridge)\nDaine Danielson (MIT/Harvard)\nCl audio Dappiaggi (Pavia)\nWojciech Dybalski (AMU Poznań)\nLaurent Freidel ( Perimeter)\nAnne-catherine De La Hamette (ETH Zürich)\nPhilipp Hoehn (OIST )\nRoberto Longo (Roma Tor Vergata)\nLeon Loveridge (U. of South-Eastern N orway)\nRainer Verch (Leipzig U.)
