论文摘要
使用数学建模方法设计了加速的玻色子冷凝物（BEC）原子发射率的角度分布的特征。在这里，我们提出了研究BEC从evanescent驻波电位（ESWP）的反射和衍射的想法。 ESWP是由在重力影响下从棱镜表面的激光束的多次反射形成的。在BEC的反射和衍射之后，由于干扰取决于我们与周期性衰减的evanevanscent Field建模的干扰，所谓的BEC密度彩虹图案形成了。加速骨气原子与表面的相互作用可以帮助证明表面结构或确定表面粗糙度，或者在二维系统中建立未来的高空间分辨率和高灵敏度磁场传感器。
The characteristic of the angular distributions of accelerated Bose-Einstein condensate (BEC) atoms incidence on the surface is designed using the mathematical modeling method. Here, we proposed the idea to study the retroreflection and diffraction of a BEC from an evanescent standing wave potential (ESWP). The ESWP is formed by multiple reflections of the laser beam from the surface of the prism under the influence of gravity. After BEC's reflection and diffraction, the so-called BEC's density rainbow patterns develop due to the interference which depends on the surface structure which we model with the periodic decaying evanescent field. The interaction of accelerated bosonic atoms with a surface can help to demonstrate surface structures or to determine surface roughness, or to build future high spatial resolution and high sensitivity magnetic-field sensors in two-dimensional systems.
