Control of the spin geometric phase in semiconductor quantum rings
Since the formulation of the geometric phase by Berry, its relevance has been demonstrated in a large variety of physical systems. However, a geometric phase of the most fundamental spin-1/2 system, the electron spin, has not been observed directly and controlled independently from dynamical phases. Here we report experimental evidence on the manipulation of an electron spin through a purely ge...
متن کاملSpin rings in bistable planar semiconductor microcavities.
A remarkable feature of exciton-polaritons is the strongly spin-dependent polariton-polariton interaction, which has been predicted to result in the formation of spin rings in real space [Shelykh, Phys. Rev. Lett. 100, 116401 (2008)]. Here we experimentally demonstrate the spin bistability of exciton polaritons in an InGaAs-based semiconductor microcavity under resonant optical pumping. We obse...
متن کاملSpin-orbit Interaction and Energy States in Nanoscale Semiconductor Quantum Rings
We study the e ect of spin-orbit iteration on the electron energy spectra in tree-dimensional (3D) nanoscale semiconductor quantum rings. Ultrasmall InAs quantum ring embedded in GaAs matrix is numerically solved with the e ective one electronic band Hamiltonian, the energyand position-dependent electron e ective mass approximation, and the spin-dependent Ben Daniel-Duke boundary conditions. Th...
متن کاملComputer simulation of electron energy state spin-splitting in nanoscale InAs/GaAs semiconductor quantum rings
In this paper, wemodel and computationally investigate the effect of spin–orbit interaction on the electron energy spectra for nanoscale semiconductor quantum rings. Our threedimensional mathematical model considers the effective one-electron band Hamiltonian, the energyand position-dependent electron effective mass approximation, and the spin-dependent Ben Daniel–Duke boundary conditions. The ...
متن کاملNuclear spin effects in semiconductor quantum dots.
The interaction of an electronic spin with its nuclear environment, an issue known as the central spin problem, has been the subject of considerable attention due to its relevance for spin-based quantum computation using semiconductor quantum dots. Independent control of the nuclear spin bath using nuclear magnetic resonance techniques and dynamic nuclear polarization using the central spin its...
