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…
Solving sign problems with physics-informed kernels
Friederike Ihssen, Renzo Kapust, Jan M. Pawlowski
In the present work we construct a novel generative architecture for systems with complex probability distributions. In general, these sampling tasks come with two challenges: reso…
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…
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…
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…
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…
