Current induced transition of anisotropic quantum Hall states
Kazumi Tsuda, Nobuki Maeda, Kenzo Ishikawa
We compare the energies of the striped Hall state and the anisotropic charge density wave (ACDW) state at half-filled third and higher Landau levels in the system with injected cur…
Induced Chern-Simons term of a paired electron state in the quantum Hall system
T. Aoyama, N. Maeda
The induced Chern-Simons term for a paired electron state is calculated in the quantum Hall system by using a field theory on the von Neumann lattice. The coefficient of the Chern-…
Photon energy absorption rate of a striped Hall gas
Y. Ishizuka, T. Aoyama, N. Maeda +1
Using symmetries of the current correlation function, we analyze the frequency dependence of the photon energy absorption rate of a striped Hall gas. Since the magnetic translation…
Intra-Landau level polarization effect for a striped Hall gas
T. Aoyama, K. Ishikawa, Y. Ishizuka +1
We calculate the polarization function including only intra-Landau level correlation effects of striped Hall gas. Using the polarization function, the dielectric function, the disp…
Field Theory of Anisotropic Quantum Hall Gas: Metrology and a Novel Quantum Hall Regime
K. Ishikawa, T. Aoyama, Y. Ishizuka +1
The von Neumann lattice representation is a convenient representation for studying several intriguing physics of quantum Hall systems. In this formalism, electrons are mapped to la…
Theory of Striped Hall Ferromagnets
Nobuki Maeda
We study spin and charge striped states at the half-filled high Landau level in the zero Zeeman energy limit using a Hartree-Fock approximation. It is shown that a ferromagnetic st…
