Title: Particle manipulation with nonadiabatic ponderomotive forces

Abstract

Average, or ponderomotive potentials effectively seen by particles in oscillating fields allow advanced techniques of particle manipulation inaccessible with static potentials. In strongly inhomogeneous fields the ponderomotive force is phase dependent, and the particle dynamics resembles that of a quantum object in a conservative barrier. Probabilistic transmission through a ponderomotive potential is then possible and can be used for particle beam slicing. Resonant fields can also cool and trap particles exhibiting natural oscillations (e.g., Larmor rotation), as well as transmit them asymmetrically; hence, acting as one-way walls. An approximate integral of particle motion is found for this case and a new ponderomotive potential is introduced accordingly.

  • The influence of space--time variations in the pumping field on the particle distribution in a plasma is studied and the distribution function is found and used to calculate the hydrodynamic parameters of the plasma. Variations in the external field are shown to induce heat and particle fluxes. The results are illustrated for a pumping field of the soliton type, for which the density of the entrainment current is estimated.
  • The characteristic features of the dynamics of particles crossing an inhomogeneous linearly polarised wave are investigated numerically and analytically. The initial particle velocity is perpendicular to the direction of propagation of the wave and its electric field vector. It was established that two ponderomotive forces, proportional to <E{sup 4}>, act on a particle crossing the wave. One of the forces, proportional to the initial velocity of the particles, deflects the beam of particles and displaces them in the direction opposed to that of the propagation of the wave. It is found that when the length and width of the inhomogeneousmore » wave are altered, the deflection and the displacement vary periodically. The ponderomotive force is maximal when the time taken by the particle to cross the wave corresponds to an integral number of half-periods of the particle vibrations. The second force has the same direction as the gradient force. Analytic expressions describing the forces acting on particles crossing a weakly inhomogeneous magnetic wave are obtained.

  • Localized regions of intense large-scale radiofrequency field are known to act like effective (''ponderomotive'') potential barriers, which scatter particles elastically and in the direction determined by the particle initial velocity rather than phase. In smaller-scale fields, transmission through a ponderomotive barrier is probabilistic and resembles tunneling of a quantum particle through a static potential. We derive asymptotic expressions for the phase-averaged transmission coefficient T as a function of the particle energy E{sub 0}. We show that, unlike for a truly quantum particle, T(E{sub 0}) is of algebraic form and has a threshold, below which transmission does not occur. We alsomore » find a threshold in E{sub 0}, above which all particles are transmitted regardless of their initial phase.« less
