abstract = {We propose a new method to calculate electric dipole
moments induced by the strong QCD θ term. The method is
based on the gradient flow for gauge fields and is free from
renormalization ambiguities. We test our method by computing
the nucleon electric dipole moments in pure Yang-Mills
theory at several lattice spacings, enabling a
first-of-its-kind continuum extrapolation. The method is
rather general and can be applied for any quantity computed
in a θ vacuum. This first application of the gradient flow
has been successful and demonstrates proof-of-principle,
thereby providing a novel method to obtain precise results
for nucleon and light nuclear electric dipole moments.},
