Significance Electron two-stream instability (ETSI) is believed to be responsible for the radio bursts observed in both the solar corona and interplanetary medium. What nonlinear kinetic processes self-consistently reconcile the several orders of magnitude difference between the short linear saturation time scale of ETSI and the long duration of bursts is fundamental in plasma turbulence and has remained unsolved for nearly 50 y. Using massive particle-in-cell simulations, we find a self… Expand

Ultrafast optical field–ionized gases—A laboratory platform for studying kinetic plasma instabilities
It is shown that following the ionization but before collisions thermalize the electrons, the plasma undergoes two-stream, filamentation, and Weibel instabilities that isotropize the electron distributions, demonstrating an easily deployable laboratory platform for studying kinetic instabilities in plasmas.
