Noise-Tolerance of Majorana Teleportation in Mesoscopic Topological Superconductors

Autor: Goto, Tsukasa, Sugeta, Masayuki, Mizushima, Takeshi, Fujimoto, Satoshi

We investigate teleportation interference associated with the non-local character of Majorana zero modes (MZMs) as a probe of MZMs focusing on the tolerance of teleportation against disturbances, such as inhomogeneous potentials at junctions and diso

Autor: Keisuke Kaneshima, Takumi Kyoda, Shuta Sugeta, Yoshihito Tanaka

Publikováno v: Journal of Synchrotron Radiation, Vol 31, Iss 4, Pp 821-828 (2024)

This study introduces a compact, portable femtosecond fibre laser system designed for synchronization with SPring-8 synchrotron X-ray pulses in a uniform filling mode. Unlike traditional titanium–sapphire mode-locked lasers, which are fixed install

Effect of surface compressive residual stress introduced by surface treatment on fatigue properties of metallic material

Autor: Arakawa Jinta, Hanaki Tatsuya, Hayashi Yoshiichirou, Akebono Hiroyuki, Sugeta Atsushi

Publikováno v: MATEC Web of Conferences, Vol 165, p 18006 (2018)

This study considers shakedown in evaluating the fatigue limit of metals with compressive residual stress at the surface. We begin by applying tension-compression fatigue tests to ASTM CA6NM under conditions of controlled load and displacement to obt

Enhanced $2\pi$-periodic Aharonov-Bohm Effect as a Signature of Majorana Zero Modes Probed by Nonlocal Measurements

Autor: Sugeta, Masayuki, Mizushima, Takeshi, Fujimoto, Satoshi

Publikováno v: J. Phys. Soc. Jpn. 92, 054701 (2023)

We propose the $2\pi$-periodic Aharonov-Bohm (AB) effect as a nonlocal probe of Majorana zero modes (MZMs) without the restriction of fermion parity. We demonstrate the enhancement of the AB effect, where the topological protection of MZMs yields amp
