Emergence of Kinetic Behavior in Streaming Ultracold Neutral Plasmas
P. McQuillen, J. Castro, S. Bradshaw +1
We create streaming ultracold neutral plasmas by tailoring the photoionizing laser beam that creates the plasma. By varying the electron temperature, we control the relative veloci…
Velocity Relaxation in a Strongly Coupled Plasma
G. Bannasch, J. Castro, P. McQuillen +2
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 ultr…
The role of collisions and strong coupling in ultracold plasmas
J. Castro, P. McQuillen, H. Gao +1
Ultracold plasmas are formed by photo-exciting clouds of cold atoms and molecules near the ionization threshold. They explore a new region of plasma physics and display effects of…
Creating and studying ion acoustic waves in ultracold neutral plasmas
T. C. Killian, P. McQuillen, T. M. O'Neil +1
We excite ion acoustic waves in ultracold neutral plasmas by imprinting density modulations during plasma creation. Laser-induced fluorescence is used to observe the density and ve…
High Resolution Ionization of Ultracold Neutral Plasmas
P. McQuillen, J. Castro, T. C. Killian
Collective effects, such as waves and instabilities, are integral to our understanding of most plasma phenomena. We have been able to study these in ultracold neutral plasmas by sh…
Creating Non-Maxwellian Velocity Distributions in Ultracold Plasmas
J. Castro, G. Bannasch, P. McQuillen +2
We present techniques to perturb, measure and model the ion velocity distribution in an ultracold neutral plasma produced by photoionization of strontium atoms. By optical pumping…
