Query: Exponential reduction of finite volume effects with twisted boundary
  conditions   Flavor-twisted boundary conditions can be used for exponential reduction of
finite volume artifacts in flavor-averaged observables in lattice QCD
calculations with $SU(N_f)$ light quark flavor symmetry. Finite volume artifact
reduction arises from destructive interference effects in a manner closely
related to the phase averaging which leads to large $N_c$ volume independence.
With a particular choice of flavor-twisted boundary conditions, finite volume
artifacts for flavor-singlet observables in a hypercubic spacetime volume are
reduced to the size of finite volume artifacts in a spacetime volume with
periodic boundary conditions that is four times larger.
