Nonlinear renewal theorems for random walks with perturbations of intermediate order
Keiji Nagai, Cun-Hui Zhang
We develop nonlinear renewal theorems for a perturbed random walk without assuming stochastic boundedness of centered perturbation terms. A second order expansion of the expected s…
Wigner formula of rotation matrices and quantum walks
Takahiro Miyazaki, Makoto Katori, Norio Konno
Quantization of a random-walk model is performed by giving a qudit (a multi-component wave function) to a walker at site and by introducing a quantum coin, which is a matrix repres…
Underground Water Cherenkov Muon Detector Array with the Tibet Air Shower Array for Gamma-Ray Astronomy in the 100 TeV Region
The Tibet AS Gamma Collaboration, M. Amenomori
We propose to build a large water-Cherenkov-type muon-detector array (Tibet MD array) around the 37,000 m Tibet air shower array (Tibet AS array) already constructed at 4,300…
Anisotropy and Corotation of Galactic Cosmic Rays
gamma Collaboration, M. Amenomori
The intensity of Galactic cosmic rays is nearly isotropic because of the influence of magnetic fields in the Milky Way. Here, we present two-dimensional high-precision anisotropy m…
Gap-mediated magnetization of a pseudo-one-dimensional system with a spin-orbit interaction
Naomichi Hatano, Ryoen Shirasaki, Hiroaki Nakamura
We argue that a pseudo-one-dimensional electron gas is magnetized when a voltage bias is applied with the Fermi level tuned to be in the energy gap generated by a spin-orbit intera…
Invariant varieties of periodic points for some higher dimensional integrable maps
Satoru Saito, Noriko Saitoh
By studying various rational integrable maps on with invariants, we show that periodic points form an invariant variety of dimension for each period…
