In our experiments we have learned a great deal about nuclear spins, and have developed new nuclear magnetic resonance (NMR) techniques for control of tiny ensembles of nuclear spins in semiconductor QDs. In III-V semiconductor nano-structures the dominant mechanism of spin information leakage to the environment (decoherence) is magnetic interaction with slowly fluctuating nuclear spins of the lattice. We are also working on the development of optical and microwave control strategies enabling fast hole and electron spin operations in single quantum dots (QDs). Notice how much more difficult it is to get tire A spinning.) If.
Now lets say the light wave encounters a simple liquid crystal molecule-its much smaller.
One of the major challenges we undertake in our studies on this subject is the realisation of spin-qubits based on single spins with coherence in the ms range. With A put it all on the outside of the tire, but on B put it on the spokes near the center. A plane polarized light wave is propagating in the direction given by the right hand rule, so lets say its electric ( E E) field is in the i i direction, the magnetic ( B B) field in the j j direction so its wavevector is in the k k direction. They also have high potential for fast coherent optical, magnetic and electrical control. Electron and hole spins in solid-state nano-structures possess unique properties with favourably long spin coherence. The new research centre at Mainz University focuses on spin phenomena because they are present in many areas of materials and fundamental science.
