Theory of the Spin Seebeck Effect at a Topological-Insulator/Ferromagnetic-Insulator Interface
Nobuyuki Okuma, Massoud Ramezani Masir, Allan H. MacDonald
The spin-Seebeck effect refers to voltage signals induced in metals by thermally driven spin currents in adjacent magnetic systems. We present a theory of the spin-Seebeck signal i…

Microscopic derivation of magnon spin current in a topological insulator/ferromagnet heterostructure
Nobuyuki Okuma, Kentaro Nomura
We investigate a spin-electricity conversion effect in a topological insulator/ferromagnet heterostructure. In the spin-momentum-locked surface state, an electric current generates…

Unconventional Spin Hall Effect and Axial Current Generation in a Dirac Semimetal
Nobuyuki Okuma, Masao Ogata
We investigate electrical transport in a three-dimensional massless Dirac fermion model that describes a Dirac semimetal state realized in topological materials. We derive a set of…
