Project Description

After trapping atoms, exciting them to an initial high-energy Rydberg state, and allowing them a brief time to exchange energy with each other through dipole-dipole interactions, we observe how their energies are redistributed among various energy levels. The measurements we make in this physical experiment do not give insight into how individual atoms interact or metrics like fidelity and entanglement entropy, which impact our results. For this reason, it is useful to compare our results from the physical experiment to those of our simulation on a supercomputer, in which we can track the final and initial energy of individual atoms and add parameters, to better explain what we observe in the physical experiment. We have refined our simulation by taking into account three body interactions, or dipole-dipole energy exchanges between three atoms at a time, in addition to the two-body interactions included in our previous model. In both our physical experiment and virtual model, we have varied the density, or number of atoms per volume within the trap, to observe its effect on the energy redistribution.
