A New Numerical Method for Topological Insulators with Strong Disorder
Yutaka Akagi, Hosho Katsura, Tohru Koma
We propose a new method to numerically compute the indices for disordered topological insulators in Kitaev's periodic table. All of the indices are kn…

Charge density wave instabilities of type-II Weyl semimetals in a strong magnetic field
Maximilian Trescher, Emil J. Bergholtz, Masafumi Udagawa +1
Shortly after the discovery of Weyl semimetals properties related to the topology of their bulk band structure have been observed, e.g. signatures of the chiral anomaly and Fermi a…

A remark on conditions that a diffusion in the natural scale is a martingale
Yuuki Shimizu, Fumihiko Nakano
We consider a diffusion processes on an interval in the natural scale. Some results are known under which is a martingale, and we give simple and analytic p…
