摘要:

研究了光晶格中旋量玻色-爱因斯坦凝聚体的静态和动态畴壁解。解析地构造了单畴壁和双畴壁解。结果表明,磁场和光致偶极相互作用对不同畴壁的形成以及畴壁宽度和畴壁速度的调节起着重要作用。此外,这些相互作用可以驱动玻色铁磁体系统的畴壁运动,类似于外部磁场或费米子铁磁体中的自旋极化电流所驱动的畴壁运动。

英文摘要:

We studied the static and dynamic domain wall solutions of spinor Bose-Einstein condensates trapped in an optical lattice. The single and double domain wall solutions are constructed analytically. Our results show that the magnetic field and light-induced dipolar interactions play an important role for both the formation of different domain walls and the adjusting of domain wall width and velocity. Moreover, these interactions can drive the motion of domain wall of Bose ferromagnet systems similar to that driven by the external magnetic field or the spin-polarized current in fermion ferromagnet.
