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…

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…

Hamiltonian approach to Yang-Mills theory in Coulomb gauge - revisited

H. Reinhardt, D. R. Campagnari, M. Leder +4

I briefly review results obtained within the variational Hamiltonian approach to Yang-Mills theory in Coulomb gauge and confront them with recent lattice data. The variational appr…

Hamiltonian approach to Coulomb gauge Yang-Mills Theory

H. Reinhardt, W. Schleifenbaum, D. Epple +1

The vacuum wave functional of Coulomb gauge Yang-Mills theory is determined within the variational principle and used to calculate various Green functions and observables. The resu…

Gauge invariance, background fields and modified Ward identities

F. Freire, D. F. Litim, J. M. Pawlowski

In this talk the gauge symmetry for Wilsonian flows in pure Yang-Mills theories is discussed. The background field formalism is used for the construction of a gauge invariant effec…

The Gauss Law Operator Algebra and Double Commutators in Chiral Gauge Theories

J. M. Pawlowski

We calculate within an algebraic Bjorken-Johnson-Low (BJL) method anomalous Schwinger terms of fermionic currents and the Gauss law operator in chiral gauge theories. The current a…
