Possible intermediate quantum spin liquid phase in α-RuCl3 under high magnetic fields up to 100 T

Autor: Xu-Guang Zhou, Han Li, Yasuhiro H. Matsuda, Akira Matsuo, Wei Li, Nobuyuki Kurita, Gang Su, Koichi Kindo, Hidekazu Tanaka

Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-7 (2023)

Abstract Pursuing the exotic quantum spin liquid (QSL) state in the Kitaev material α-RuCl3 has intrigued great research interest recently. A fascinating question is on the possible existence of a field-induced QSL phase in this compound. Here we pe

Decision-making deficits in obsessive-compulsive disorder are associated with abnormality of recency and response consistency parameter in prospect valence learning model

Autor: Keitaro Murayama, Hirofumi Tomiyama, Aikana Ohno, Kenta Kato, Akira Matsuo, Suguru Hasuzawa, Kenta Sashikata, Mingi Kang, Tomohiro Nakao

Publikováno v: Frontiers in Psychiatry, Vol 14 (2023)

BackgroundPatients with obsessive-compulsive disorder (OCD) have deficits in decision-making in the Iowa Gambling Task (IGT). However, no study has investigated the parameters of the prospect valence learning (PVL) model in the IGT for OCD.AimsThis s

Spin-glass transition in the spin–orbit-entangled J eff = 0 Mott insulating double-perovskite ruthenate

Autor: Hayato Yatsuzuka, Yuya Haraguchi, Akira Matsuo, Koichi Kindo, Hiroko Aruga Katori

Publikováno v: Scientific Reports, Vol 12, Iss 1, Pp 1-6 (2022)

Abstract We have successfully synthesized new Ru4+ double perovskite oxides SrLaInRuO6 and SrLaGaRuO6, which are expected to be a spin–orbit coupled J eff = 0 Mott insulating ground state. Their magnetic susceptibility is much significant than that

High-Speed Tracking with Mutual Assistance of Feature Filters and Detectors

Autor: Akira Matsuo, Yuji Yamakawa

Publikováno v: Sensors, Vol 23, Iss 16, p 7082 (2023)

Object detection and tracking in camera images is a fundamental technology for computer vision and is used in various applications. In particular, object tracking using high-speed cameras is expected to be applied to real-time control in robotics. Th

Inverse Association Between Resting-State Putamen Activity and Iowa Gambling Task Performance in Patients With Obsessive-Compulsive Disorder and Control Subjects

Autor: Suguru Hasuzawa, Hirofumi Tomiyama, Keitaro Murayama, Aikana Ohno, Mingi Kang, Taro Mizobe, Kenta Kato, Akira Matsuo, Kazufumi Kikuchi, Osamu Togao, Tomohiro Nakao

Publikováno v: Frontiers in Psychiatry, Vol 13 (2022)

BackgroundSymptoms of obsessive-compulsive disorder (OCD) have been conceptualized as manifestations of decision-making deficits. Patients with OCD exhibit impairment during the decision-making process, as assessed by the Iowa Gambling Task (IGT). Th

Gapless spin liquid in a square-kagome lattice antiferromagnet

Publikováno v: Nature Communications, Vol 11, Iss 1, Pp 1-7 (2020)

There exist many theoretical models of frustrated quantum magnetism, most of which lack convincing experimental realisations. Here the authors combine several experimental methods to argue that KCu6AlBiO4(SO4)5Cl behaves as a square-kagome-lattice qu
