We have developed a consistent theory of the Heisenberg quantum antiferromagnet in the disordered phase with a short range antiferromagnetic order on the basis of the path integral for spin coherent states. We have presented the Lagrangian of the theory in a form which is explicitly invariant under rotations and found natural variables in terms of which one… CONTINUE READING
