    Velocity Relaxation in a Strongly Coupled Plasma
    (American Physical Society, 2012) Bannasch, G.; Castro, J.; McQuillen, P.; Pohl, T.; Killian, T.C.; Rice Quantum Institute
    Collisional relaxation of Coulomb systems is studied in the strongly coupled regime. We use an optical pump-probe approach to manipulate and monitor the dynamics of ions in an ultracold neutral plasma, which allows direct measurement of relaxation rates in a regime where common Landau-Spitzer theory breaks down. Numerical simulations confirm the experimental results and display non-Markovian dynamics at early times.
