Flat-band Majorana bound states in topological Josephson junctions
Autor: Daisuke Oshima, Satoshi Ikegaya, Andreas P. Schnyder, Yukio Tanaka
Publikováno v: Physical Review Research, Vol 4, Iss 2, p L022051 (2022)
Nodal topological superconductors characterized by p_{x}-wave pairing symmetry host flat-band Majorana bound states causing drastic anomalies in low-energy electromagnetic responses. Nevertheless, the study of flat-band Majorana bound states has been

A Study of Turbulence Simulations Using Finite Difference Lattice Boltzmann Method
Autor: Daisuke OSHIMA, Michihisa TSUTAHARA, Satoshi MIZUTANI
Publikováno v: Journal of Fluid Science and Technology, Vol 2, Iss 3, Pp 582-591 (2007)
Three-dimensional homogeneous isotropic turbulence is simulated using the finite difference lattice Boltzmann method (FDLBM). First, we analyze the characteristics of numerical viscosity of FDLBM, and present a method in which the numerical viscosity

Spin Hall conductivity in topological Dirac semimetals
Autor: Masatoshi Sato, Yukio Tanaka, Tatsuki Hashimoto, Katsuhsia Taguchi, Yusuke Yamaguchi, Daisuke Oshima
We theoretically investigate the spin Hall conductivity (SHC) in topological Dirac semimetals (TDSMs) whose Dirac points are protected by rotational symmetry. On the basis of a general phase diagram of the system with time-reversal, inversion and fou

An evaluation study on advanced public transport priority system using traffic simulation
Autor: Takashi Oguchi, Takane Imagawa, Akira Mitsuyasu, Daisuke Oshima
Publikováno v: International Journal of Urban Sciences. 21:43-53
For the reasons of environmental issues, congestion mitigation, and vulnerable road users, the surface mass public transport (PT) system in urban area should be improved and promoted in Japan. This paper provides an overview of the current state of p

Unconventional gate voltage dependence of the charge conductance caused by spin-splitting Fermi surface by Rashba-type spin-orbit coupling
Autor: Yukio Tanaka, Daisuke Oshima, Katsuhisa Taguchi
We calculate the gate voltage (Vg) dependence of charge conductance in a normal metal (NM)/two dimensional electron gas (2DEG) junction, where Rashba spin-orbit coupling and ferromagnetism exist in the 2DEG. We call this 2DEG as the ferromagnetic Ras

Tunneling Conductance in Two-Dimensional Junctions between a Normal Metal and a Ferromagnetic Rashba Metal
Autor: Yukio Tanaka, Daisuke Oshima, Katsuhisa Taguchi
Publikováno v: Journal of the Physical Society of Japan. 87:034710
We have studied charge transport in ferromagnetic Rashba metal (FRM), where both Rashba type spin-orbit coupling (RSOC) and exchange coupling coexist. It has nontrivial metallic states, i.e., normal Rashba metal (NRM), anomalous Rashba metal (ARM), a
