The x-ray diffraction study of 12 nm CeO2 was carried out up to-40 GPa using an angle dispersive synchrotron-radiation in a diamond-anvil cell with different pressure transmitting medium (PTM) (4:1 methanol: ethanol mixture, silicone oil and none) at room temperature.While the cubic fluorite-type structure CeO2 was retained to the highest pressure, there is progressive broadening and intensity reduction of the reflections with increasing pressure.

对比了这两种常用的基于李雅普诺夫稳定性理论的量子系统控制方法.一种是基于距离的李雅普诺夫控制方法,另一种方法是基于偏差的李雅普诺夫控制方法.这两种控制方法都是基于不同几何意义的李雅普诺夫控制函数,但它们之间存在一定的差异.我们研究了在MATLAB环境下,对二能级粒子系统进行数值仿真实验.
集成化量子光路由于尺寸更小、稳定性更高、可扩展性更强已被广泛应用于量子通信、量子计算等领域[1].但目前大多集成量子光路都是无源光子芯片,需要外界输入量子光源,同时集成二者的有源光子芯片的报道并不多.近期,我们实验组成功的在铌酸锂光子芯片内同时实现了光子路径纠缠的产生及操控.这里我们详细报道铌酸锂波导中纠缠光子产生的基本特性,包括其产率、频谱、温度-波长调谐特性等.
基于如热光[1]、准热光[2]等混乱光源的二阶HBT干涉特性,亚波长干涉[3]、鬼成像[4]、非定域干涉[5]、二阶Talbot自成像[6]等一系列有趣的二阶干涉效应被人们所报道.值得注意的是,这些基于混乱光的二阶干涉效应与混乱光的特性息息相关,即光源面是由大量连续分布的独立点光源构成的.
掺镨硅酸钇晶体是一种被广泛应用于量子相干效应的固体光学材料,2013年在此晶体中利用电磁感应透明(EIT)将光脉冲的存储寿命延长至1分钟的量级[1],使得掺镨硅酸钇晶体在光信息处理方面具有很好的实际应用前景.偏振是光携带信息的一个重要的自由度,但是由于晶体的双折射以及镨离子吸收的各向异性,使得在固体中对光波偏振态的调控变得复杂.目前关于在固体中EIT对偏振态影响的研究相对较少,大量研究工作主要是在
