Role of Bound Magnon in Magnetic Domain Wall Motion
Tae-Suk Kim, J. Ieda, S. Maekawa
We report on a quantum description of the domain wall (DW) motion under a spin current. A bound magnon, which is the zero mode of DW, is found to play a dominant role in DW dynamic…
Multicomponent Bright Solitons in F = 2 Spinor Bose-Einstein Condensates
Masaru Uchiyama, Jun'ichi Ieda, Miki Wadati
We study soliton solutions for the Gross--Pitaevskii equation of the spinor Bose--Einstein condensates with hyperfine spin F=2 in one-dimension. Analyses are made in two ways: by a…
Magnetic memory and current amplification devices using moving domain walls
S. E. Barnes, J. Ieda, S. Maekawa
A moving magnetic domain wall produces an electromotive force (emf). It is therefore possible to read the state of a magnetic memory device via the emf it produces when subject to…
Dark solitons in F=1 spinor Bose--Einstein condensate
Masaru Uchiyama, Jun'ichi Ieda, Miki Wadati
We study dark soliton solutions of a multi-component Gross--Pitaevskii equation for hyperfine spin F=1 spinor Bose--Einstein condensate. The interactions are supposed to be inter-a…
Inverse scattering method for square matrix nonlinear Schrödinger equation under nonvanishing boundary conditions
Jun'ichi Ieda, Masaru Uchiyama, Miki Wadati
Matrix generalization of the inverse scattering method is developed to solve the multicomponent nonlinear Schrödinger equation with nonvanishing boundary conditions. It is shown th…
Matter-Wave Solitons in an F=1 Spinor Bose-Einstein Condensate
Jun'ichi Ieda, Takahiko Miyakawa, Miki Wadati
Following our previous work [J. Ieda, T. Miyakawa, M. Wadati, cond-mat/0404569] on a novel integrable model describing soliton dynamics of an F=1 spinor Bose--Einstein condensate,…
