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 BornOppenheimer 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 CasimirPolder 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.
