In this talk, I present a general and powerful strategy for solving integration-by-parts (IBP) identities, which take the form of multivariable linear homogeneous relations among Feynman integrals. Our diagonalisation approach transforms the IBP system into effectively single-variable recurrence relations. This diagonal structure exposes the analytic behaviour of the reduction and provides a...

Generalised Gibbs Ensembles (GGEs) appear in a wide range of contexts, from statistical physics to black hole thermodynamics and holography. They are constructed by inserting higher-spin conserved charges into a theory’s partition function. A 2D Conformal Field Theory partition function is a modular invariant, so it is natural to ask about the modular properties of the GGE. In some cases this...
