Renormalization group methods are a key element of theoretical particle physics and may also be central for constructing a fundamental theory of gravity, e.g., based on Weinberg’s asymptotic safety conjecture. The aim of this program is to bring together theorists and phenomenologists in order to discuss ideas related to the application of the renormalization group in quantum gravity and the consequences of asymptotic safety for cosmology, black holes and a possible ultraviolet completion of the standard model of particle physics including gravity.

[Timetable - available from start of the program]


This meeting will focus on three broadly defined topics: Structural aspects of asymptotic safety, phenomenological implications of asymptotic safety in gravity and particle physics, and relations of asymptotically safe quantum gravity to other approaches to quantum gravity. Each topic will be addressed by several talks outlining the present status of the research program and possibly opening up new perspectives. The schedule will contain ample room for discussion and collaboration.

There will be approximately five talks per day, with the exception of Wednesday afternoon, which is reserved for in-depth discussion.

Travel Reimbursement

PhD students and young Postdoc fellows are eligible for travel grants to participate in the program. If you are interested in such a grant, please mark the corresponding field in the application form, briefly summarize your interest in the program in the comments field, and indicate an estimation of your expected travel expenses. Since only a limited number of grants is available, decision concerning the grants will be made on a case-by-case basis and you will be notified shortly after the application deadline.


Nordita provides a limited number of rooms in the Stockholm apartment hotel BizApartments free of charge for accepted participants.
