REPULSIVE MULTIPOLE-MULTIPOLE INTERACTIONS
Abstract
The research objective is to experimentally and theoretically study the fundamental repulsive electric multipole-multipole interactions. As shown in this proposal, these interactions are based on one of the four fundamental force s: Coulomb force. One type of well known electric multipole-multipole interactions is the van der Waals interaction or the second-order dipole-dipole interaction. Van der Waals interactions are investigated in different disciplines, such as physics, chemistry, biology, and other fields of sciences. A common misconception about van der Waals interactions is that they are known as attractive interactions. This is only true for ground state atoms. For excited atoms, van der Waals interactions can be repulsive. Since the discovery of van der Waals interactions in the 1870s, repulsive van der Waals interactions have been rarely studied until recently. The main objective of this proposal is to study the fundamental repulsive higher-order multipole-multipole interactions. Specifically, the repulsive dipole-quadrupole, quadrupole-quadrupole, and dipole-octopole interactions will be investigated in cold Rydberg gases.
