Title: Fixed Points of the Renormalisation Group Flow of Yukawa Couplings & CP Violation in the Standard Model, and Beyond
Abstract: The 1-loop RG flow of the CKM matrix in the Standard model will be presented and the fixed points isolated. This includes the RG running of the Jarlskog invariant and fixed points of CP violation. The analysis is equally applicable to the PMNS matrix in the leptonic sector, with three sterile right-handed Dirac neutrinos, but the nature of the flow is different for normal and inverted hierarchies of neutrino masses.

![Constraints and Aperiodicity
STP, DIAS Mini Symposium - 4 November 2025
Speaker: Felix Flicker (University of Bristol, UK)
Abstract: Some of the most important phenomena in physics arise when correlations emerge from local constraints. I will outline results for a range of constrained models in the new setting of aperiodic tilings. On the Ammann Beenker tiling we prove the existence of Hamiltonian cycles (visiting each vertex precisely once), and thereby solve a range of problems including the three-colouring problem and the travelling salesperson problem [1]. On the recently discovered ‘Spectre’ aperiodic monotiling we exactly solve the interacting quantum dimer model [2]. I will highlight recent and ongoing work in which we generalise these results to random graphs. This ongoing work includes the development of a new machine learning approach (RSMI-NE) for studying constrained models in large networks without periodicity [3].
