Surface-localized topological superconductivity in nodal-loop materials: BdG analysis
Takeru Matsushima, Hiroki Tsuchiura
We theoretically study surface superconductivity in a nodal-line semimetal by combining a minimal tight-binding model with a layer-resolved Bogoliubov-de Gennes approach. In the no…
Sensor free, self regulating thermal switching via anomalous Ettingshausen effect and spin reorientation in DyCo5
Shibo Wang, Hiroki Tsuchiura, Nobuaki Terakado
We propose a sensor free, self regulating thermal switch that combines the anomalous Ettingshausen effect (AEE) with a temperature driven spin reorientation transition (SRT) in the…
New insights into the magnetism of DyCo
Alena Vishina, Konstantin Skokov, Hiroki Tsuchiura +5
In this work, we present the first magnetization measurements of DyCo single crystals in magnetic fields up to 14 T, spanning a temperature range up to 600 K. Our investigation…
Josephson Diode Effect for a Kitaev Ladder System
Cheng-Rong Xie, Hiroki Tsuchiura, Manfred Sigrist
We study the Josephson diode effect realized purely by geometry in a Kitaev-ladder Josephson junction composed of two parallel spinless -wave chains coupled by an interleg hoppi…
Anisotropy in magnetoelastic effects of YCo5
Jun-ichiro Inoue, Hiroki Tsuchiura
We develop the phenomenological theory for uniaxial ferromagnets, and derive explicit formulae for their magnetostriction (MS) and magnetic anisotropy energy (MAE) generated by the…
