武汉物数所理论交叉学术交流系列报告 (第一三四期) The Casimir effect in atomic, molecular, and optical physics Prof. James F. Babb Institute of Theoretical Atomic, Molecular and Optical Physics, Harvard-Smithsonian Center for Astrophysics, USA 2015年11月19日(周四) 下午3:00-4:30 频标楼4楼报告厅 About the Speaker: James F. Babb is a senior scientific staff of the Institute for the Theoretical Atomic, Molecular and Optical Physics (ITAMP) at the Harvard-Smithsonian Center for Astrophysics. He graduated with PhD degree from the New York University, USA, then He received ITAMP postdoctoral Fellow. Current research interest: Spectroscopy and scattering in atomic and molecular physics for applications to astrophysics, light science, and ultra-low temperature collisions; Calculations of long-range forces between pairs of atoms, and between atoms and conducting walls; Quantum electro dynamical studies of energy shifts arising from two transverse photon exchange leading to experimental verification by measurements on Rydberg states of helium; Theories of effects beyond the Born- Oppenheimer approximation and their manifestations, such as in the hyperfine structure of the hydrogen molecular ions. Abstract: The Casimir effect is commonly defined as the change in the interaction energy or force between two plates in the absence of external fields. For microscopic systems, like atoms and molecules, a similar effect is seen, where the Casimir-Polder potential appears in the case, for example, of two ground-state systems that are well-separated with respect to the wavelength of a photon characterizing a system's energy. I will discuss the theory and calculation of the Casimir-Polder potential for several cases of interest in atomic, molecular, and optical physics. 主办单位:武汉物数所理论与交叉研究部
