Weight-Space Physics: Interpretable Hypernetworks for Lattice Quantum Field Theories
Tobias Göbel, Julian R. Ebelt, Zier Mensch, Mathis Gerdes, Miranda C. N. Cheng
Lattice field theory is the workhorse of non-perturbative physics, used to simulate phenomena from the strong nuclear force to critical phenomena in materials. Its Boltzmann distributions are parametrized analytically by coupling constants, but these bare parameters are weak pred…
