Electron Momentum Distributions for 4a1 Orbitals of CFxCl4-x in Low Momentum Region: a Possible Evidence of Molecular Geometry Distortion 下载免费PDF全文
由于低动量区域理论和实验的严重差异,重新分析了系列氟利昂分子CF3Cl、CF2Cl2和CFCl3 (CFxCl4-x, x=1~3)的4a1轨道的电子动量分布. 利用分子离子的平衡几何构型计算得到的动量分布很大地改善了,与实验数据之间的吻合,这一结果表明在p<0.5 a.u.区域实验观测到的偏高的动量分布值可能是电离瞬间分子构型的扭曲带来的. 进一步的分 相似文献

A cavity quantum electrodynamics scheme for preparing a genuinely entangled state [A. Borras, et al., J. Phys. A 40 (2007) 13407] on six two-level atoms is proposed. In the scheme, the atom-cavity detuning is much bigger than the atom-cavity coupling strength and the necessary preparation time is much shorter than the Rydberg-atom lifespan. Hence the scheme has two distinct features, i.e., insensitive to the cavity decay and the atom radiation. 相似文献

The simplified four-qubit cluster state (i.e., (|0000〉 + |0011〉 + |1100〉 -|1111〉)/2) is explored for splitting an arbitrary single-qubit quantum information (QI). Various feasible distributions of the four qubits among the Q,I sender and receivers for tri-splitting or hi-splitting are found out. For the distribution representations the corresponding splitting schemes and their LOCCs (local operation and classical communication) are presented amply while others are mentioned concisely. 相似文献

Two tripartite schemes are put forward with shared entanglements and Local Operation and Classical Communication (LOCC) for sharing an operation on a remote target sate.The first scheme uses a Bell and a symmetric W states as quantum channels,while the second replaces the symmetric W state by an asymmetric one.Both schemes are treated and compared from the aspects of quantum resource consumption,operation complexity,classical resource consumption,success probability and efficiency.It is found that the latter scheme is better than the former one.Particularly,the sharing can be achieved only probabilistically with the first scheme deterministically with the second one. 相似文献
