Superfluid current in 3He-A at T = 0

In order to obtain the supercurrent in 3He-A at T = 0, Gor'kov's equations are solved exactly for an order parameter linearized with respect to spatial variations. We obtain various nonanalytical second-order corrections to the standard expression. In the current perpendicular to l, we find a p contribution Vertical Barl x curllVertical Bar(curll)/sub perpendicular/. In the current parallel to l, we have a term Vertical Barl x curllVertical Bar[v/sup s/-(h/4m)curll (-circumflex)=/sub parallel/ and another one Vertical Barl x curllVertical Bar(partial/sub x/l/sub y/+partial/sub y/l/sub x/), where the x and y axes are along (curl l)/sub perpendicular/ and l x curll
