On spherical designs obtained from -polynomial association schemes
Sho Suda
We characterize that the image of the embedding of the -polynomial association scheme into eigenspace by primitive idempotent is a spherical -design in terms of the Kre…
Renormalized Landau Levels and Particle-Hole Symmetry in Graphene
Yafis Barlas, Wei-Cheng Lee, Kentato Nomura +1
In this proceedings paper we report on a calculation of graphene's Landau levels in a magnetic field. Our calculations are based on a self-consistent Hartree-Fock approximation for…
Legendrian framings for two-bridge links
Sebastian Baader, Masaharu Ishikawa
We define the Thurston-Bennequin polytope of a two-component link as the convex hull of all pairs of integers that arise as framings of a Legendrian representative. The main result…
6Li/7Li estimates for metal-poor stars
A. E. Garcia Perez, W. Aoki, S. Inoue +3
The presence of the lithium-6 isotope in some metal-poor stars is a matter of surprise because of the high values observed. Non-standard models of Big Bang nucleosynthesis and pre-…
On nonparametric and semiparametric testing for multivariate linear time series
Yoshihiro Yajima, Yasumasa Matsuda
We formulate nonparametric and semiparametric hypothesis testing of multivariate stationary linear time series in a unified fashion and propose new test statistics based on estimat…
Epitaxial-strain effect on charge/orbital order in Pr0.5Ca0.5MnO3 films
D. Okuyama, M. Nakamura, Y. Wakabayashi +7
Effect of growth orientation on charge- and orbital-ordering (CO-OO) phenomena has been studied for Pr0.5Ca0.5MnO3 epitaxial thin films fabricated on (LaAlO3)0.3-(SrAl0.5Ta0.5O3)0.…
