Spin Magneton and Spin Waves of Bose-Einstein condensates in an optical lattice |
| |
| Abstract: | The spin magneton and spin waves of Bose-Einstein condensates in an optical lattice are studied in detail. Spin magneton and Spontaneous magnetization are found. By using classical method, the spin waves and energy levels in an uniform system are obtained, as well as the spin wavers tuned by laser and energy levels are found. Especially, by applying continuum limit, Mathieu function waves and energy levels are given. |

| Keywords: | Bose-Einstein condensates spin magneton spin wave Mathieu function wave |
