We investigate numerically the photoluminescence (PL) spectrum in the integer quantum Hall regime and find that the electron spins play important roles. The spectra for the left circularly polarized light show peak splittings when the Fermi levels lies in the excited Landau level, which is caused by

In order to realize Hofstadter's butter y and Quantum Hall e ect (QHE) in 3D systems as proposed previously (Phys. Rev. Lett. 86 (2001) 1062), we consider a system that has the ÿeld induced spin density wave (FISDW) phases. By extending the 2D FISDW model for an organic conductor to 3D, we show that
We present several novel quasi-two-dimensional electron systems with an additional degree of freedom. These include systems which contain two or more layers of electrons in close proximity so that interlayer Coulomb interactions are strong, and thick-layer electron systems in wide parabolic wells. T
