We are pleased to announce that the next ITMP seminar will be held on Wednesday, Nov 3, at 18:00 (Moscow time). It will be arranged via zoom.
Speaker: Dr. Mikhail Ivanov, Princeton IAS & INR RAS
Title: Love and Naturalness
Abstract: Tidal Love numbers of a compact body capture multipole moments induced by external gravitational fields. Also they appear as Wilson coefficients in the post-Newtonian effective field theory of extended objects. It has been known for a decade that Love numbers vanish identically for black holes in four dimensions, which posed a major naturalness problem in the EFT context. In my talk, I will present a new hidden (“Love”) symmetry of black holes, which elegantly resolves this naturalness paradox.
