Landau damping
This course was taught in the summer of 2010 in the Centre International des Rencontres Mathématiques as part of a program on mathematical plasma physics related to the ITER project; it constitutes an introduction to the Landau damping phenomenon in the linearized and perturbative nonlinear regimes, following the recent work [78] by Mouhot & Villani.
متن کاملNonlinear electron Landau damping of ion-acoustic solitons
Several authors have treated kinetic effects associated with the ion-acoustic soliton; e.g., Ott and Sudan investigated linear electron Landau damping and Karpman and Lotko have looked at damping due to ion reflection. Here an O'Neil-type frozen wave calculation that includes effects associated with electron orbits in a soliton is presented. This calculation differs from previous ones in that t...
متن کاملLandau Damping and Entropy
It is shown that the well-known LANDAu-damping entropy paradox can be resolved by considering a macroscopic entropy as defined by CLAUSIUS instead of the microscopic entropy defined by BOLTZMANN. Although both entropy definitions are identical for equilibrium configurations, the same in general is not true for non-equilibrium configurations. To extend the entropy definition of CLAUSIUS to non-e...
متن کاملEffect of flow damping on drift-tearing magnetic islands in tokamak plasmas
A systematic fluid theory of nonlinear drift-tearing magnetic island dynamics in a conventional large aspect-ratio lowcircular cross-section tokamak plasma is derived from a set of single-helicity reduced neoclassical-magnetohydrodynamical equations which incorporate electron and ion diamagnetic flows, ion gyroviscosity, poloidal and toroidal flow damping, cross flux-surface momentum and partic...
متن کاملOn Landau Damping
Going beyond the linearized study has been a longstanding problem in the theory of Landau damping. In this paper we establish exponential Landau damping in analytic regularity. The damping phenomenon is reinterpreted in terms of transfer of regularity between kinetic and spatial variables, rather than exchanges of energy; phase mixing is the driving mechanism. The analysis involves new families...
