Description
We apply twisted boundary conditions to off-shell Rome-Southampton
non-perturbative renormalisation. This enables us to select momenta
that are not necessarily a Fourier mode. The technique allows
better controlled continuum extrapolation of results by removing
O(4) breaking ambiguity. Continuity of the momentum scale allows us to develop a
step-scaling technique that does not require fine tuning of the coupling.
