Finite-amplitude RF heating rates for magnetized electrons in neutral plasma
John M Guthrie, Jacob L Roberts
A theoretical model is developed and evaluated using a Vlasov-Poisson treatment to calculate radiofrequency (RF) electric field heating rates for magnetized electrons in neutral pl…
Nanosecond-timescale development of Faraday rotation in an ultracold gas
Jonathan R. Gilbert, Mark A. Watkins, Jacob L. Roberts
When a gas of ultracold atoms is suddenly illuminated by light that is nearly resonant with an atomic transition, the atoms cannot respond instantaneously. This non-instantaneous r…
Many-body collision contributions to electron momentum damping rates in a plasma influenced by electron strong coupling
Puchang Jiang, John Guthrie, Jacob L. Roberts
Experimental studies of electron-ion collision rates in an ultracold neutral plasma (UNP) can be conducted through measuring the rate of electron plasma oscillation damping. For su…
Evaluation of Charged Particle Evaporation Expressions in Ultracold Plasmas
Craig Witte, Jacob L. Roberts
Electron evaporation plays an important role in the electron temperature evolution and thus expansion rate in low-density ultracold plasmas. In addition, evaporation is useful as a…
Observation of a strong coupling effect on electron-ion collisions in ultracold plasmas
Wei-Ting Chen, Craig Witte, Jacob L. Roberts
Ultracold plasmas (UCP) provide a well-controlled system for studying multiple aspects in plasma physics that include collisions and strong coupling effects. By applying a short el…
A scalable theoretical mean-field model for the electron component of an ultracold neutral plasma
John Guthrie, Jacob Roberts
The electron component of an ultracold neutral plasma (UCP) is modeled based on a scalable method using a self-consistently determined mean-field approximation. Representative samp…
