Stress tensor Coulombic system

The reader should appreciate the difference between the previous expression and the last term on the right side of Eq. (F.71). This difference arises because, for a dipolar system, = JZili / independent of Sy, whereas for a Coulomb system, My depends on Sy as one can verify from Eq. (F.69). The diagonal component of the total stress tensor is then obtained by adding the three contributions given in Eqs. (F.91), (F.93), and (F.94) [see Eqs. (F.89) and (F.90)]. 

Regarding the stress tensor of the system, the (Coulomb) components corresponding to the two orthogonal directions parallel to the walls (i.e., 7 = x,y) can be calculated exactly as in the three-dimensional case (see Appendix F.1.2.2). On the other hand, the normal component (7 = z) is given by...
