【摘要】：随着纳米技术的发展,人类操控物质的尺度达到了微纳米尺度。在这个尺度下,真空电磁场的力学效应变得非常重要,甚至成为决定一个物理系统动力学演化特性的主要相互作用力。在真空电磁场的力学效应中,原子间共振相互作用以及卡西米尔-波耳德相互作用是两类非常令人感兴趣的现象；前者在量子存储、量子传输和制造量子光源方面有着应用价值,而后者在制造原子反射镜和量子悬浮设备中扮演重要角色。由于集成光学技术和原子芯片技术的发展,在量子光学实验中,原子样品可能非常接近于某种材料的表面；在此情况下,不但原子之间的相互作用会受到材料表面的影响,原子样品本身也会与材料表面之间发生较强的相互作用。因此,研究材料表面对原子-原子相互作用的影响以及材料表面的性质对原子-表面相互作用的影响,并讨论如何利用这种影响调控原子-原子以及原子-表面间的相互作用是一个非常有意义的课题。然而,目前在这一问题上还缺乏详细深入的研究。基于上述考虑,我们开展了研究工作并得到以下成果：1、我们推导了位于材料表面附近的二原子间共振相互作用的形式理论；对镜面反射和漫反射表面这两种情况作了分类讨论；我们的计算结果表明原子间共振相互作用可以分为由自由电磁真空贡献的部分和材料表面反射波所贡献的部分,其中后者提供了利用材料表面操控原子间共振相互作用的可行性。以上内容给出在第二章中。2、我们将原子共振相互作用和原子芯片相结合,研究了二个原子处于一个电介质材料平面附近时的共振相互作用。我们发现当原子对非常接近于电介质平面时(k0z1),原子间的相互作用势能和能量转移率发生显著地增强；我们将这一效应称为“近表面效应”。对近表面效应的利用将有助于制造新型量子光源和量子存储装置。这些内容给出在第三章中。3、我们将原子共振相互作用和集成光学以及纳米技术相结合,讨论了利用单层纳米圆柱阵列调控原子间相互作用。使用大折射率材料制造的亚波长尺寸微纳米结构已经广泛应用于电磁波的操控；在本文中,我们提出将其用于操控原子之间的共振相互作用。利用纳米圆柱阵列对电磁波散射性质可调的特点,我们不再需要改变原子到材料表面的距离,而只需改变纳米圆柱之间的距离(或者说光栅常数),就能够打开或关闭原子之间的共振相互作用和能量交换,这对于控制量子态的定向传输有着重大应用价值。这些内容在第四章中介绍。4、我们将卡西米尔-波耳德相互作用和超材料相结合,研究了利用具有特殊电磁散射性质的材料来改变基态原子与材料表面间的卡西米尔-波耳德相互作用。我们讨论了一种具有电磁负反射性质的材料,并计算了这种负反射表面与基态原子之间的卡西米尔-波耳德相互作用。根据我们的计算结果,负反射现象可用于产生排斥性的卡西米尔-波耳德相互作用力,而这对制造原子反射镜和量子悬浮装置有重要应用意义。这些内容在第五章中介绍。
[Abstract]:With the development of nanotechnology, the scale of human manipulation material reaches the micro nano scale. At this scale, the mechanical effect of the vacuum electromagnetic field becomes very important, and even becomes the main interaction force determining the dynamic evolution characteristics of a physical system. In the mechanical effect of the vacuum electromagnetic field, the interatomic resonance interaction And kimier - Polish interaction is the two very interesting phenomenon; the former is valuable in quantum storage, quantum transmission and manufacture of quantum light sources, and the latter plays an important role in the manufacture of atomic reflectors and quantum suspension devices. In optical experiments, the atomic sample may be very close to the surface of a material; in this case, not only the interaction between atoms is affected by the surface of the material, but also the strong interaction between the atomic sample itself and the surface of the material. Therefore, the effect of the surface of the material on the atom atom interaction and the material are studied. The effect of the properties of the material surface on the interaction of atomic surface and how to use this effect to regulate the interaction between atoms and atoms and the interaction between atoms and surfaces is a very meaningful subject. However, there is still a lack of detailed and in-depth study on this issue. 1, we deduce the form theory of the resonance interaction between two atoms near the surface of the material, and classify the two cases of the mirror reflection and the diffuse reflection surface; our calculation results show that the interatomic resonance interaction can be divided into the part of the free electromagnetic vacuum contribution and the reflection wave on the surface of the material. The part of the contribution, which provides the feasibility of manipulating the interatomic resonance interaction with the surface of the material, is given in the second chapter in the second chapter. We combine the atomic resonance interaction with the atomic chip to study the resonance interaction of two atoms near the flat surface of a dielectric material. The atomic pair is very close to the dielectric plane (k0z1), the interaction potential energy and the energy transfer rate between atoms are significantly enhanced; we call this effect "near surface effect". The use of near surface effects will help to produce new quantum light sources and quantum storage devices. These contents are given in the third chapter,.3, we By combining atomic resonance interaction with integrated optics and nanotechnology, a single layer nanocylindrical array is used to regulate interatomic interaction. The sub wavelength micro nanostructures made of large refractive index materials have been widely used in the manipulation of electromagnetic waves. In this paper, we propose to use it to manipulate atoms. The resonance interaction. Using the nano cylindrical array for the adjustable electromagnetic scattering properties, we no longer need to change the distance between the atom to the surface of the material, but only by changing the distance between the nanometers (or the grating constant), the resonance interaction and energy exchange between the atoms can be opened or closed, which is the control amount.

We have studied the interaction of Casimir - Polish interaction with supermaterials and studied the interaction of cassiamer - Polish interaction between the ground state atoms and the material surface by using the materials with special electromagnetic scattering properties. The kcimier - Polish interaction between the negative reflection surface and the ground state atom is calculated and the negative reflection can be used to produce the repulsive kcimier - Polish interaction force, which is important for the fabrication of the atomic reflector and the quantum suspension device.
