9988566Korepin An electron was the first elementary particle known to physisists. The charge of an electron was discoverd in 1897 and the spin in 1925. The project is devoted to a study of a separation between charge and spin of the electron in strongly correlated systems. The Hubbard model was suggested in 1966 to describe strong interaction of electrons in solids. The project suggests to study charge and spin separation of the electron by means of exact analitical solution of the Hubbard model.

电子是物理学家所知道的第一个基本粒子。电子的电荷在1897年被发现，自旋在1925年被发现。本项目致力于研究强相关系统中电荷与电子自旋之间的分离。1966年提出了哈伯德模型来描述固体中电子的强相互作用。本项目建议利用Hubbard模型的精确解析解来研究电子的电荷和自旋分离。
