DESCRIPTION:Speakers: Friederike Ihssen (Heidelberg University)\n\nIn my t
 alk I discuss physics-informed renormalisation group flows [1]\, which con
 sist of general\, scale-dependent coordinate transformations in field spac
 e and an associated target action in terms of this novel field. The pair o
 f the target action and field transformation complement the standard formu
 lation of the Wetterich renormalisation group (RG) flows in terms of the e
 ffective action and shows great potential both for conceptual as well as c
 omputational applications. I will map out some selected applications such 
 as the quantitative description of instanton-dominated tunnelling processe
 s in the anharmonic oscillator [2] or recipes for the construction of gaug
 e-invariant RG flows [3].\n \n[1] F. Ihssen and J. M. Pawlowski\; arxiv:2
