  • The nonlinear final state of short-pulse lasers is examined using fully explicit particle-in-cell simulations. A new long-wavelength hosing instability is found to be dominant after a few Rayleigh lengths of propagation. This instability causes self-trapped electrons to be displaced off axis; we find that ion motion is important at the highest densities studied. A possible explanation for this instability is given based on a new variational principle analysis for short-pulse lasers propagating in underdense plasma. {copyright} {ital 1999} {ital The American Physical Society}
  • The electron hosing instability in the blow-out regime of plasma-wakefield acceleration is investigated using a linear perturbation theory about the electron blow-out trajectory in Lu et al. [in Phys. Rev. Lett. 96, 165002 (2006)]. The growth of the instability is found to be affected by the beam parameters unlike in the standard theory Whittum et al. [Phys. Rev. Lett. 67, 991 (1991)] which is strictly valid for preformed channels. Particle-in-cell simulations agree with this new theory, which predicts less hosing growth than found by the hosing theory of Whittum et al.

  • Transverse stability of the drive beam is critical to plasma wakefield accelerators. A long, relativistic particle beam propagating in an overdense plasma is subject to beam envelope modulation and hosing (centroid displacement) instabilities. Coupled equations for the beam centroid and envelope are derived. The growth rate for beam hosing is examined including return current effects (where the beam radius is of order the plasma skin depth) in the long-beam, strongly-coupled, overdense regime.
  • Equations describing the quasilinear stage of Jeans instability in a stellar disk are derived and solved analytically. Some possible astrophysical applications are discussed briefly.
