Demonstration of a heterogeneously integrated III-V/SOI single wavelength tunable laser.
Optics Express, 2013 A heterogeneously integrated III-V-on-silicon laser is reported, integrating a III-V gain section, a silicon ring resonator for wavelength selection and two silicon Bragg grating reflectors as back and front mirrors.

Charge and spin Hall effect in graphene with magnetic impurities
, 2009 We point out the existence of finite charge and spin Hall conductivities of graphene in the presence of a spin orbit interaction (SOI) and localized magnetic impurities.

Role of d orbitals in the Rashba-type spin splitting for noble-metal surfaces
, 2012 We investigate the Rashba-type spin splitting in the Shockley surface states on Au(111) and Ag(111) surfaces, based on first-principles calculations. By turning on and off spin-orbit interaction (SOI) partly, we show that although the surface states are ...

Energy levels of a parabolically confined quantum dot in the presence of spin-orbit interaction
, 2004 We present a theoretical study of the energy levels in a parabolically confined quantum dot in the presence of the Rashba spin-orbit interaction (SOI). The features of some low-lying states in various strengths of the SOI are examined at finite magnetic ...

, 2011 Persistent, oscillatory charge and spin currents are shown to be driven by a two-component terahertz laser pulse in a one-dimensional mesoscopic ring with Rashba-Dresselhaus spin orbit interactions (SOI) linear in the electron momentum.

Impact of climate change on Southeast Asian natural habitats, with focus on protected areas
Global Ecology and Conservation, 2022 Natural habitats have been destroyed by anthropogenic factors for several decades, exacerbated by climate change. This study investigated the impact of climate change on natural habitats by using 55 Phasianidae species.

, 2009 We show that an initially unpolarized electron flow acquires spin polarization after passing through a lateral barrier in two-dimensional (2D) system with spin-orbit interaction (SOI) even if the current is directed normally to the barrier. The generated

The relation of the Dzyaloshinskii-Moriya interaction to spin currents and to the spin-orbit field
, 2017 Starting from the general Berry phase theory of the Dzyaloshinskii-Moriya interaction (DMI) we derive an expression for the linear contribution of the spin-orbit interaction (SOI). Thereby, we show analytically that at the first order in SOI DMI is given
