Nuclear matter and its interaction is described through quantum chromodynamics. Today, understanding this dynamics is what drives the progress in describing nature at its smallest scales. This new understanding is derived from large scale numerical simulations of the full non perturbative theory through lattice quantum field theory.
For example, the recent breakthroughs in the calculation of the anomalous magnetic moment of the muon, also presented at this meeting, are through lattice simulations. Their input impacts physics from nuclear applications, e.g. proton properties, parton distributions and multi-nucleon interactions, to the early universe and searches for new fundamental physics beyond the standard model.
The key to lattice simulations are the configurations, snap-shots of quantum space-time, that all these interesting observables are calculated on. In this contribution I present recent, new perspectives on generating these snap-shots. I will show how we can go towards novel master-field simulations that push up the size of the space-time volume generated by an order of magnitude. I will also present how the new collaborative effort, OpenLat, that we founded, can enable access to state-of-the art configurations to the lattice community and how this leads to new and exciting results in broad applications in the future.
