Finite-Size Corrections to the Excitation Energy Transfer in a Massless Scalar Interaction Model
Nobuki Maeda, Tetsuo Yabuki, Yutaka Tobita +1
We study the excitation energy transfer (EET) for a simple model in which a massless scalar particle is exchanged between two molecules. We show that a finite-size effect appears i…
Meissner effect in the layered Kane-Mele model with Hubbard interaction
Jun Goryo, Nobuki Maeda
We investigate the magnetic response in the quantum spin Hall phase of the layered Kane-Mele model with Hubbard interaction, and argue a condition to obtain the Meissner effect. Th…
The London Equation in Quantum Spin Hall System with Electronic Correlation
Jun Goryo, Nobuki Maeda
The Kane-Mele (KM) model is proposed to describe the quantum spin Hall effect of electrons on the two-dimensional honeycomb lattice. Here, we will show that, in a certain parameter…
Magnetic Response in Quantized Spin Hall Phase of Correlated Electrons
Jun Goryo, Nobuki Maeda
We investigate the magnetic response in the quantized spin Hall (SH) phase of layered-honeycomb lattice system with intrinsic spin-orbit coupling lambda_SO and on-site Hubbard U. T…
(De)confinement of supercurrent in Z_2 Topological Insulators
Jun Goryo, Nobuki Maeda, Ken-Ichiro Imura
It is shown that the electric supercurrent flows in a Z_2 topological insulator with U_em(1) X U_z(1) (electromagnetic and spin) gauge symmetries. When U_z(1) is broken, a dissipat…
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…
