Modeling molecules with constraints
Charles F. F. Karney, Jason E. Ferrara
Techniques for simulating molecules whose conformations satisfy constraints are presented. A method for selecting appropriate moves in Monte Carlo simulations is given. The resulti…
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 Stochastic Systems
Charles F. F. Karney
In recent years, there has been considerable interest in understanding the motion in Hamiltonian systems when phase space is divided into stochastic and integrable regions. This pa…
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…
