| 中文摘要 | Introducing the Dyson-Maleev transformation and the coherent state ansatz, we obtain two partial differential equations of motion with non-linear coupling in an order-parameter-preserving antiferromagnet (OPP-AFM). These equations are reduced to a single non-linear Schrodinger equation by using the method of multiple scales combined with the long-wavelength approximation. The single-soliton solution and the two-soliton bound-state solution are obtained using the inverse-scattering transformation. These results show that soliton-like magnon localization and two-magnon bound states in the FCC-AFM compound CeAs are possible. The possibility of observing a pp soliton in this system are also di |
