Compression of Atomic Phase Space Using an Asymmetric One-Way Barrier
M. G. Raizen, A. M. Dudarev, Qian Niu +1
We show how to construct asymmetric optical barriers for atoms. These barriers can be used to compress phase space of a sample by creating a confined region in space where atoms ca…
Differential Form of the Collision Integral for a Relativistic Plasma
Bastiaan J. Braams, Charles F. F. Karney
The differential formulation of the Landau-Fokker-Planck collision integral is developed for the case of relativistic electromagnetic interactions.
Fokker-Planck and Quasilinear Codes
Charles F. F. Karney
The interaction of radio-frequency waves with a plasma is described by a Fokker-Planck equation with an added quasilinear term. Methods for solving this equation on a computer are…
Current in Wave Driven Plasmas
Charles F. F. Karney, Nathaniel J. Fisch
A theory for the generation of current in a toroidal plasma by radio-frequency waves is presented. The effect of an opposing electric field is included, allowing the case of time v…
Efficiency of Current Drive by Fast Waves
Charles F. F. Karney, Nathaniel J. Fisch
The Rosenbluth form for the collision operator for a weakly relativistic plasma is derived. The formalism adopted by Antonsen and Chu can then be used to calculate the efficiency o…
Long-Time Correlations in the Stochastic Regime
Charles F. F. Karney
The phase space for Hamiltonians of two degrees of freedom is usually divided into stochastic and integrable components. Even when well into the stochastic regime, integrable orbit…
