RETRACTED: Chiral Majorana fermion modes in a quantum anomalous Hall insulator–superconductor structure

…, G Yin, J Wang, B Lian, Q Zhou, ES Choi, K Murata… - Science, 2017 - science.org
Majorana fermion is a hypothetical particle that is its own antiparticle. We report transport
measurements that suggest the existence of one-dimensional chiral Majorana fermion modes …

Scale-invariant quantum anomalous Hall effect in magnetic topological insulators beyond the two-dimensional limit

…, L Pan, M Lang, Y Jiang, Q Shao, T Nie, K Murata… - Physical review …, 2014 - APS
We investigate the quantum anomalous Hall effect (QAHE) and related chiral transport in the
millimeter-size (Cr 0.12 Bi 0.26 Sb 0.62) 2 Te 3 films. With high sample quality and robust …

[HTML][HTML] Plasma and synovial fluid microRNAs as potential biomarkers of rheumatoid arthritis and osteoarthritis

K Murata, H Yoshitomi, S Tanida, M Ishikawa… - Arthritis research & …, 2010 - Springer
Introduction MicroRNAs (miRNAs), endogenous small noncoding RNAs regulating the activities

[HTML][HTML] Comprehensive microRNA analysis identifies miR-24 and miR-125a-5p as plasma biomarkers for rheumatoid arthritis

K Murata, M Furu, H Yoshitomi, M Ishikawa, H Shibuya… - PloS one, 2013 - journals.plos.org
MicroRNAs (miRNAs) are present in human plasma and known as a non-invasive biomarker
for cancer detection. Our study was designed to identify plasma miRNAs specific for …

Electrical Detection of Spin-Polarized Surface States Conduction in (Bi0.53Sb0.47)2Te3 Topological Insulator

J Tang, LT Chang, X Kou, K Murata, ES Choi… - Nano …, 2014 - ACS Publications
Strong spin–orbit interaction and time-reversal symmetry in topological insulators enable
the spin-momentum locking for the helical surface states. To date, however, there has been …
