Detailed Description

Parallel transport a lattice field.

Description:

Suppose q(x) is a quark field. Displacement operator D_j^{(p)} moves quark field for p lattice sites to the direction j in covariant fashion.

Namely, D_j^{(p)} q(x) = U_j(x) U_j(x+j) U_j(x+2j)...U_j(x+(p-1)j) q(x+pj), where U is the gauge-link.

dir: x(0), y(1), z(2)
