This paper studies the propagation of dipole solitons in
highly nonlocal medium by using the variational method. It finds
that the dipole solitons will be stable when the input power obeys a
restrict value. When the incident power does not satisfy the stable
conditions, the nonlocal accessible dipole solitons will undergo
linear harmonic oscillation. It shows such evolution behaviours in
detail. 相似文献

采用直流磁控溅射和后退火氧化的方法在掺铝氧化锌(AZO)导电玻璃上制备了二氧化钒(VO2)薄膜,研究了不同的退火温度、退火时间对VO2/AZO复合薄膜制备的影响,并对复合薄膜的结构、组分、光电特性进行了测试与分析. 结果表明,导电玻璃上的AZO没有改变VO2的取向生长,但明显改变了VO2薄膜的表面形貌特征. 与用相同工艺和条件在普通玻璃基底上制备的VO2薄膜相比,VO2/AZO复合薄膜的相变温度降低约25 ℃,热滞回线宽度收窄至6 ℃,相变前后可见光透过率均在50%以上,1500 nm处红外透过率约为55%和21%,电阻率变化达3 个数量级. 该复合薄膜表面平滑致密,制备工艺简单,性能稳定,可应用于新型光电器件.

The previous protocols of remote quantum information concentration were focused on the reverse process of quantum telecloning of single-qubit states. We here investigate the reverse process of optimal universal 1→2 telecloning of arbitrary two-qubit states. The aim of this telecloning is to distribute respectively the quantum information to two groups of spatially separated receivers from a group of two senders situated at two different locations. Our scheme shows that the distributed quantum information can be remotely concentrated back to a group of two different receivers with 1 of probability by utilizing maximally four-particle cluster state and four-particle GHZ state as quantum channel. 相似文献

运用第一性原理杂化泛函研究了本征缺陷(O空位和Ga空位)对于β-Ga2O3的几何结构和电子性质的影响.计算结构表明:杂化泛函B3LPY能很好的描述β-Ga2O3的几何结构和电子结构,能与实验符合.含O缺陷的形成能在富氧和贫氧下分别为4.04和0.92 eV,优于含Ga缺陷的体系.空位缺陷的出现对于理想Ga2O3的晶格参数影响不显著,只是在O空位体系中,空位附近Ga-O键长有0.1?变化.含空位缺陷的体系的禁带中都有缺陷能级的出现,含Ga和O空位缺陷的Ga2O3的光跃迁能分别为1.93 eV(β自旋)和2.92 eV,有很明显的光吸收的拓展,从理论上解释了Ga2O3作为光催化材料的潜在应用. 相似文献
