Spin filtering in transition-metal phthalocyanine molecules from first principles
Li Niu, Huan Wang, Lina Bai +4
Using first-principles calculations based on density functional theory and the nonequilibrium Green function formalism, we studied the spin transport through metal-phthalocyanine (…
Voltage-Controlled Negative Index in Vertically Coupled Quantum Dot Systems
Huan Wang, Ka-Di Zhu
We demonstrate that voltage-controlled negative index can be obtained in self-organized InAs quantum dot systems. As the bias voltage changes, the refractive index can be adjusted…
Berry Phase in a Single Quantum Dot with Spin-Orbit Interaction
Huan Wang, Ka-Di Zhu
Berry phase in a single quantum dot with Rashba spin-orbit coupling is investigated theoretically. Berry phases as functions of magnetic field strength, dot size, spin-orbit coupli…
Voltage-Controlled Berry Phases in Two Coupled Quantum Dots
Huan Wang, Ka-Di Zhu
The voltage-controlled Berry phases in two vertically coupled InGaAs/GaAs quantum dots are investigated theoretically. It is found that Berry phases can be changed dramatically fro…
