Thermal Hall transport in Kitaev spin liquids
Tsuyoshi Okubo, Joji Nasu, Takahiro Misawa +1
We investigate the thermal Hall conductivity in the Kitaev model with additional interactions under a magnetic field, employing a finite-temperature tensor network method benchmark…

Spin Current Generation Controlled by the Néel State in a Compensated Ferrimagnet
Xin Theng Lee, Takahiro Misawa, Mamoru Matsuo +1
Compensated ferrimagnets, which break sublattice and time-reversal symmetries in the ground state, exhibit an isotropic ferromagnet-like spin splitting despite a vanishing net magn…

What is a proper definition of spin current? -- Lessons from the Kane-Mele Model
Tomohiro Tamaya, Takeo Kato, Takahiro Misawa
Spin current, a key concept in spintronics that carries spin angular momentum, has a non-unique definition due to the non-conservation of spins in solids. While two primary definit…
