21. In the saddle-point approximation this approach reduces to that of G. Kotliar and A. E. Ruckenstein [Phys. Rev. Lett. 57, 1362 (1986)]. However, in the KR approach only the (Formula presented) component of the spin operator can be defined and hence the spin-rotation invariance is broken already on the Hamiltonian level.
