Non-uniqueness of boundary-value problems in Renormalization Group flows
Astrid Eichhorn, Zois Gyftopoulos, Aaron Held
The Renormalization Group flow connects microscopic to macroscopic descriptions of a system and is therefore typically considered as an initial-value problem. Motivated by situatio…
Quark and lepton mixing in the asymptotically safe Standard Model
Astrid Eichhorn, Zois Gyftopoulos, Aaron Held
The quark mixing (CKM) matrix is near-diagonal, whereas the lepton mixing (PMNS) matrix is not. We learn that both observations can generically be explained within an ultraviolet c…
Asymptotic safety meets tensor field theory: towards a new class of gravity-matter systems
Astrid Eichhorn, Razvan Gurau, Zois Gyftopoulos
Combining asymptotically safe quantum gravity with a tensor field theory, we exhibit the first example of a theory with gravity and scalar fields in four dimensions which may reali…
