• Stochastic ion heating. One of the path-breaking applications of stochasticity to plasma physics, this work established stochastic ion heating as an important mechanism for the absorption of lower hybrid waves by ions. A prediction of this theory was a two-temperature ion distribution, which was subsequently verified experimentally on Petula and other tokamaks.

• General stochasticity. These papers describe the transition to stochasticity, focusing on the behavior of stochastic orbits near islands. The second paper (my most cited) uncovered the long correlations that can arise when stochastic orbits wander close to islands.

• Basic plasma physics. These papers provide an elegant generalization of the “Rosenbluth potential” formulation to relativistic plasmas. Previously the relativistic collision operator was only known in an unwieldy integral formulation (Beliaev and Budker, 1956). The second paper is an example of the application of the new formulation to the calculation of the electrical conductivity of a plasma.

• Numerical methods. The first paper is a review of Fokker-Planck codes as applied to rf heating. The second describes special techniques for high accuracy calculations of stochastic orbits.

• Current drive. Here are the definitive numerical studies of rf current drive for a variety of situations, and noteworthy for the careful attention paid to the posing of the problem. Through the use of the adjoint formulation, the current drive efficiency can be calculated quickly, elegantly and accurately. The sixth paper is a classic in comparing theory and experiment.
