| Abstract: | The phenomenon of spontaneous symmetry breaking is well known. It is known to be accompanied with the appearance of the “Goldstone boson”. In this paper we construct the canonical coordinates of the Goldstone boson, for quantum spin systems with short range as well as long range interactions.
