项目摘要

This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).In this experimental program highly excited atoms are exposed to microwave fields with two goals. The first is to understand how a many level atomic system interacts with a radiation field over a broad range of atomic states, from one in which the frequency is low compared to the intrinsic atomic frequency to one in which the frequency is high compared to the atomic frequency, high enough that the absorption of one photon can ionize the atom. In some regimes the response of the atom is better described classically and in others quantum mechanically. Understanding the connections between the two different descriptions is a major goal. The second is to manipulate and control the properties of atoms by varying the polarization, frequency and amplitude of microwave fields to which they are exposed. An understanding of this control in both classical and quantum terms is sought.The broad impacts of this work are several. First, it is likely to lead to new and useful insights into the connections between classical and quantum mechanics. Such insights are particularly useful to physicists and chemists, and they are of wide popular interest. Manipulating and controlling excited atoms is of great current interest for anti hydrogen and quantum computing research, and it is an excellent prototype system for laser manipulation of molecules of interest in physical chemistry.

该奖项是根据2009年美国复苏和再投资法案（公法111-5）资助的。在这个实验计划中，高度激发的原子暴露在微波场中，有两个目标。第一个是了解多能级原子系统如何在广泛的原子态范围内与辐射场相互作用，从频率与固有原子频率相比较低的原子态到频率与原子频率相比较高的原子态，高到足以使一个光子的吸收可以使原子发光。在某些情况下，原子的响应更好地用经典描述，而在另一些情况下则用量子力学描述。理解两种不同描述之间的联系是一个主要目标。第二种是通过改变原子所暴露的微波场的偏振、频率和振幅来操纵和控制原子的性质。在这两个经典和量子控制的理解是寻求。这项工作的广泛影响是几个。首先，它可能会为经典力学和量子力学之间的联系带来新的有用见解。这些见解对物理学家和化学家特别有用，并且引起了广泛的兴趣。操纵和控制激发态原子是当前反氢和量子计算研究的重要内容，它是物理化学中感兴趣的分子的激光操纵的优秀原型系统。
