| 英文摘要 | The nu = 2/5 state is spin unpolarized at weak magnetic field and fully polarized at strong field. At intermediate field, a plateau of half the maximal polarization is observed. We study this phenomenon in the framework of composite fermion (CF) theory. Due to the mixing of the CF Landau levels (LLs), the unidirectional charge/spin density wave state of CFs is lower in energy than the Wigner crystal. This means that transport anisotropy, similar to that for electrons in higher Landau levels at half-filling, may appear in this fractional quantum Hall state when the external magnetic field is in an appropriate range. When the magnetic field is tilted, the easy transport direction is perpendicular to the direction of the in-plane field. Varying the partial filling factor of CF LLs from 0 to 1, we find that the energy minimum occurs in the vicinity of a half. |
