Controlling soliton excitations in Heisenberg spin chains through the magic angle
发表期刊PHYSICAL REVIEW E
关键词Ferromagnetic Chain Systems Magnons States Field
摘要We study the nonlinear dynamics of collective excitation in an N-site XXZ quantum spin chain, which is manipulated by an oblique magnetic field. We show that, when the tilted field is applied along the magic angle, theta(0)=+/- arccos root 1/3, the anisotropic Heisenberg spin chain becomes isotropic and thus an freely propagating spin wave is stimulated. Also, in the regime of tilted angles larger and smaller than the magic angle, two types of nonlinear excitations appear: bright and dark solitons.
