论文摘要
带有量子机械和经典场的双腔位于双裂缝后面，以分析波粒对偶性。这两个磁场都有常见的节点和抗inodes，在越过双缝线后，三层原子通过该节点。当原子越过一个共同的抗鼻脉，可以在量子场的阶段记录路径信息时，原子场相互作用是最大的。另一方面，如果原子越过一个共同的节点，则相互作用为null且没有路径信息。量子场上的正交测量值可以揭示原子之后的路径，具体取决于其初始幅度$α$和经典的幅度$ \ varepsilon $。在本报告中，我们表明，经典的辐射就像干扰和衍射模式的聚焦元素，以及它如何改变可见性和区分。此外，在我们的双关闭方案中，这两个可能的途径与内部原子状态相关，这使我们能够考虑不同情况下的并发和波粒偶性之间的关系。
A double cavity with a quantum mechanical and a classical field is located immediately behind of a double-slit in order to analyse the wave-particle duality. Both fields have common nodes and antinodes through which a three-level atom passes after crossing the double-slit. The atom-field interaction is maximum when the atom crosses a common antinode and path-information can be recorded on the phase of the quantum field. On other hand, if the atom crosses a common node, the interaction is null and no path-information is stored. A quadrature measurement on the quantum field can reveal the path followed by the atom, depending on its initial amplitude $α$ and the classical amplitude $\varepsilon$. In this report we show that the classical radiation acts like a focusing element of the interference and diffraction patterns and how it alters the visibility and distinguishabilily. Furthermore, in our double-slit scheme the two possible paths are correlated with the internal atomic states, which allows us to study the relationship between concurrence and wave-particle duality considering different cases.
