Valley-dependent spin transport in monolayer transition-metal dichalcogenides
Yuya Ominato, Junji Fujimoto, Mamoru Matsuo
We study valley-dependent spin transport theoretically in monolayer transition-metal dichalcogenides in which a variety of spin and valley physics are expected because of spin-vall…
Quantum Oscillations of Gilbert Damping in Ferromagnetic/Graphene Bilayer Systems
Yuya Ominato, Mamoru Matsuo
We study the spin dynamics of a ferromagnetic insulator on which graphene is placed. We show that the Gilbert damping is enhanced by the proximity exchange coupling at the interfac…
Phase diagram of a magnetic topological nodal semimetal: Stable nodal line in an easy-plane ferromagnet
Yuya Ominato, Ai Yamakage, Kentaro Nomura
We study a topological phase diagram of a ferromagnetic topological nodal semimetal. We consider a lattice model for three-dimensional topological insulators with ferromagnetic ord…
Electric polarization in magnetic topological nodal semimetal thin films
Yuya Ominato, Ai Yamakage, Kentaro Nomura
We theoretically study the electric polarization in magnetic topological nodal semimetal thin films. In magnetically doped topological insulators, topological nodal semimetal phase…
Spin-orbit crossed susceptibility in topological Dirac semimetals
Yuya Ominato, Shuta Tatsumi, Kentaro Nomura
We theoretically study the spin-orbit crossed susceptibility of topological Dirac semimetals. Because of strong spin-orbit coupling, the orbital motion of electrons is modulated by…
Orbital magnetism of graphene flakes
Yuya Ominato, Mikito Koshino
Orbital magnetism is studied for graphene flakes with various shapes and edge configurations using the tight-binding approximation. In the low-temperature regime where the thermal…
