These states exhibit true long-range spiral order that spontaneously breaks the U(1) invariance of the Hamiltonian. Besides breaking a continuous symmetry in d=1 , this spiral ordering has ...<br/><img src="http://prola.aps.org/graphics/rapid30x30.gif" width="30" height="30" alt="Rapid Communication"/><br/>[Phys.
