Topological superconductivity in bilayer Rashba system
Sho Nakosai, Yukio Tanaka, Naoto Nagaosa
We theoretically study a possible topological superconductivity in the interacting two layers of Rashba systems, which can be fabricated by the hetero-structures of semiconductors…
Spin-to-charge conversion in lateral and vertical topological-insulator/ferromagnet heterostructures with microwave-driven precessing magnetization
Farzad Mahfouzi, Naoto Nagaosa, Branislav K. Nikolic
Using the charge-conserving Floquet-Green function approach to open quantum systems driven by external time periodic potential, we analyze how spin current pumped (in the absence o…
On the nature of the optical conductivity of polaron
G. De Filippis, V. Cataudella, A. S. Mishchenko +1
We study theoretically a fundamental issue in solids: the evolution of the optical spectra of polaron as the electron-phonon coupling increases. By comparing the exact results obta…
Charge pumping by magnetization dynamics in magnetic and semi-magnetic tunnel junctions with interfacial Rashba or bulk extrinsic spin-orbit couplings
Farzad Mahfouzi, Jaroslav Fabian, Naoto Nagaosa +1
We develop a time-dependent nonequilibrium Green function (NEGF) approach to the problem of spin pumping by precessing magnetization in one of the ferromagnetic layers within F/I/F…
Skyrmion quantum numbers and quantized pumping in two dimensional topological chiral magnets
Bohm-Jung Yang, Naoto Nagaosa
We investigate the general conditions to achieve the adiabatic charge and spin polarizations and quantized pumping in 2D magnetic insulators possessing inhomogeneous spin structure…
Evolution of Edge States and Critical Phenomena in the Rashba Superconductor with Magnetization
Ai Yamakage, Yukio Tanaka, Naoto Nagaosa
We study Andreev bound states (ABS) and resulting charge transport of Rashba superconductor (RSC) where two-dimensional semiconductor (2DSM) heterostructures is sandwiched by spin-…
