Conditional value-at-risk under reward-penalty mechanism with applications to robust portfolio management
Jun Cai, Tiantian Mao, Zhiqiao Song
In this paper, we present robust portfolio selection models by incorporating a reward and penalty mechanism into portfolio management. We assume that the joint distribution of the…
Josephson phase shift and diode effect due to the inverse spin Hall effect
Gen Tatara, Yositake Takane, Aurelien Manchon
We theoretically study the direct and inverse spin Hall effects in a superconductor-normal metal-uperconductor junction induced by a spin-orbit interaction that is invariant under…
A quantum picture of light-suppressed photosynthetic charge transfer
Guang Yang, Gen Tatara
We propose a dynamic mechanism for the reversible regulation of photosynthesis in varying light environments. We employ a three-level quantum model to take into account the correla…
Effect of spin-conserving scattering on Gilbert damping in ferromagnetic semiconductors
K. Shen, G. Tatara, M. W. Wu
The Gilbert damping in ferromagnetic semiconductors is theoretically investigated based on the - model. In contrast to the situation in metals, all the spin-conserving scatte…
Microscopic Theory of Current-Spin Interaction in Ferromagnets
H. Kohno, S. Kawabata, T. Noguchi +3
Interplay between magnetization dynamics and electric current in a conducting ferromagnet is theoretically studied based on a microscopic model calculation. First, the effects of t…
Spin torque and force due to current for general spin textures
Gen Tatara, Hiroshi Kohno, Junya Shibata +2
Non-adiabatic correction to spin transfer torque arising from fast-varying spin texture is calculated treating conduction electron fully quantum mechanically. The torque is non-loc…
