Incompressible Liquid, Stripes and Bubbles in rapidly rotating Bose atoms at
Hidetsugu Seki, Kazusumi Ino
We numerically study the system of rapidly rotating Bose atoms at the filling factor (ratio of particle number to vortex number) with the dipolar interaction. A moderate dipo…
Critical Spectra and Wavefunctions of a One-dimensional Quasiperiodic System
Kazusumi Ino, Mahito Kohmoto
We numerically study a one dimensional quasiperiodic system obtained from two dimensional electrons on the triangular lattice in a uniform magnetic field aided by the multifractal…
Critical Level Statistics of the Fibonacci Model
Michihiro Naka, Kazusumi Ino, Mahito Kohmoto
We numerically analyze spectral properties of the Fibonacci model which is a one-dimensional quasiperiodic system. We find that the energy levels of this model have the distributio…
Statistics of Spectra for One-dimensional Quasi-Periodic Systems at the Metal-Insulator Transition
Yoshihiro Takada, Kazusumi Ino, Masanori Yamanaka
We study spectral statistics of one-dimensional quasi-periodic systems at the metal-insulator transition. Several types of spectral statistics are observed at the critical points,…
Random Matrix Theory Analysis of Cross Correlations in Financial Markets
Akihiko Utsugi, Kazusumi Ino, Masaki Oshikawa
We confirm universal behaviors such as eigenvalue distribution and spacings predicted by Random Matrix Theory (RMT) for the cross correlation matrix of the daily stock prices of To…
Supersymmetry and d-Wave Superconductivity
Kazusumi Ino
Motivated by a recent development in the field theory of the fractional quantum Hall effect, we propose a supersymmetric field theoretical model of quantum critical d-wave and (d+i…
