Generative sampling with physics-informed kernels
Friederike Ihssen, Renzo Kapust, Jan M. Pawlowski
We construct a generative network for Monte-Carlo sampling in lattice field theories and beyond, for which the learning of layerwise propagation is done and optimised independently…
Functional Renormalization Group Flows and Gauge Consistency in QED
Yoshio Echigo, Yuji Igarashi, Katsumi Itoh +2
We consider quantum electrodynamics with chiral four-Fermi interactions in the functional renormalization group approach. In gauge theories, the functional flow equation for the ef…
A comprehensive approach to the physics of mesons
Angel. S. Miramontes, Jose M. Morgado Chavez, Joannis Papavassiliou +1
We develop a novel approach for the self-consistent solution of coupled sets of Bethe-Salpeter and Schwinger-Dyson equations in QCD. This framework allows us to maintain the axial…
Physics-informed operator flows and observables
Friederike Ihssen, Jan M. Pawlowski
We discuss physics-informed renormalisation group flows (PIRGs) for general operators. We show that operator PIRGs provide a comprehensive access to all correlation functions of th…
Tunneling with physics-informed RG flows in the anharmonic oscillator
Alfio Bonanno, Friederike Ihssen, Jan M. Pawlowski
We solve the anharmonic oscillator with physics-informed renormalisation group (PIRG) flows, with an emphasis on the weak coupling regime with its instanton-dominated tunnelling pr…
Physics-informed gauge theories
Friederike Ihssen, Jan M. Pawlowski
We use the physics-informed renormalisation group (PIRG) for the construction of gauge invariant renormalisation group flows. The respective effective action is a sum of a gauge in…
