Description

In the Euclidean path-integral formalism, the theta-term introduces a sign problem which makes direct investigation difficult. On the other hand, the theta-term can be included in a Hamiltonian formulation straightforwardly - as long as one can deal with the infinite dimensional Hilbert space. In this contribution we present an investigation into the 3+1d SU(3) Yang Mills action with nonzero theta-term using Neural Network quantum states.
