Chapter 3 is devoted to the derivation of the master equation for the system. We find that the depasing time T2Q PCis about 100 ns when the spin decoherence is only induced by the QPC, and the repeated QPC measurement will slow down the transition rate between spin states which can be interpreted in terms of quantum Zeno effect.Meanwhile, we also study the effect of QPC measurement on two-electron spin state in double quantum dot system.

Properties of frontier orbital of xanthogen formates and ethoxycarbonyl thionocarbamates, including HOMO energy, shape of HOMO and atomic HOMO density, were calculated with quantum chemistry programs GW03 and FUJISTU CAChe. According to the results, the relationship between selectivity of such two kinds of collectors and their quantum chemical indices was investigated to discuss the feasibility of applying them in screening chalcopyrite collectors.

Our investigation has shown that:ⅰ there was an interference effect between the incident and reflected matter waves as all the atoms in BECs were coherent;ⅱ considering the rotation of a vortex, the nonuniform velocity distribution along the surface would play an important role in the quantum reflection process. For example, they would change the characteristics of the interference fringes between the incident and reflected matter waves;ⅲ the reflected vortex became unstable for sufficiently low incident velocity or strong interaction. This sort of instability physically originated from dynamics excitations induced by the atomic interaction in the quantum reflection process.

我们的研究表明：ⅰ由于相干性质的存在，在涡旋与固体表面相互作用的过程中，被固体表面反射回去的部分与正在入射的部分在空间叠加后一定会产生清晰的干涉条纹；ⅱ由于各向异性的速度分布，涡旋的反射率也呈各向异性，因此反射回来的部分与入射部分形成的干涉条纹宽度以及疏密程度与入射速度以及速度各向异性的程度有关；ⅲ由于玻色凝聚体中原子间相互作用的存在，反射过程中凝聚体会产生激发，破坏涡旋的结构，使得反射后的涡旋不再是中心对称。

For the first time, we investigated the possibility of using non-minimal coupled scalar field (include Real and Complex scalar fields) as the candidate of dark energy---Quintessence or Phantom. A cosmological model droved by real scalar field with accelerating and decelerating, forever cycling and expanding was constructed. Classical and quantum wormholes with Tachyon fields were discussed in detail. The entropy of sphere symmetric black holes due to arbitrary spin fields was studied, and the proportional relations between entropy and fields degeneracy was derived. For the first time, we investigated the neutrino quasinormal modes of stationary black holes in the background of de Sitter space-time, and the quasinormal modes of Schwarzschild black holes with arbitrary spin fields. We also studied the quantum teleportation in the background of curved space-time for the first time.
