Relativistic ponderomotive Hamiltonian of a Dirac particle in a vacuum laser field
D. E. Ruiz, C. L. Ellison, I. Y. Dodin
We report a point-particle ponderomotive model of a Dirac electron oscillating in a high-frequency field. Starting from the Dirac Lagrangian density, we derive a reduced phase-spac…
Nonlinear frequency shift of electrostatic waves in general collisionless plasma: unifying theory of fluid and kinetic nonlinearities
Chang Liu, Ilya Y. Dodin
The nonlinear frequency shift is derived in a transparent asymptotic form for intense Langmuir waves in general collisionless plasma. The formula describes both fluid and kinetic e…
Ladder Climbing and Autoresonant Acceleration of Plasma Waves
Ido Barth, Ilya Y. Dodin, Nathaniel J. Fisch
When the background density in a bounded plasma is modulated in time, discrete modes become coupled. Interestingly, for appropriately chosen modulations, the average plasmon energy…
Lagrangian geometrical optics of nonadiabatic vector waves and spin particles
D. E. Ruiz, I. Y. Dodin
Linear vector waves, both quantum and classical, experience polarization-driven bending of ray trajectories and polarization dynamics that can be interpreted as the precession of t…
On the correspondence between quantum and classical variational principles
D. E. Ruiz, I. Y. Dodin
Classical variational principles can be deduced from quantum variational principles via formal reparameterization of the latter. It is shown that such reparameterization is possibl…
