Project Description

In our project we ran computations on a supercomputer to simulate experiments performed on highly excited atoms at μK temperatures. At μK temperatures the atoms are moving slowly so there are essentially no collisions of the atoms on the time scales at which we perform our experiments. In the absence of collisions the atoms exchange energy through long range dipole-dipole interactions. This exchange depends on the distances between and relative orientation of the atoms. The angular dependence between two atoms has recently been studied experimentally¹ . We simulate experimentally accessible spatial arrangements to see if the effect of the angular dependence can be measured in the many atom case. We present results that show that the angular dependence has a measurable effect on the time evolution of the spatial distribution of the energy in the system.
