Rogue waves, presented in numerous fields of science, are attracting significant attention. We study the excitation of electromagnetic rogue waves in magnetized plasmas caused by the thermal electron anisotropic loss cone distribution. The Krylov-Bogoliubov-Mitropolsky method is used to derive the n…

This study addresses the question: how bright can one make a beam with nontrivial quantum correlations such as entanglement or squeezing? The authors consider a nonlinear mechanism in plasmas, namely four wave mixing to make polarization-entangled photon pairs. The discovery of stable high intensity “quantum light” in plasmas opens the door to remarkable applications, including enhanced x-ray imaging, quantum (sub-Rayleigh) lithography, and greatly improved quantum communication.

The fundamental theoretical problem of the existence of plasma equilibrium in a nonsymmetric magnetic field with nested magnetic surfaces is resolved. The lack of examples of smooth solutions to the equilibrium equations with no symmetry of the configuration has for many years served as the argument…

We have experimentally studied the formation of shock waves in a laser-induced annular configuration. By locating an aluminum target in the focal plane of a 109W/cm2 laser, an annular plasma is formed that acts as a piston for a shock wave in a background gas composed by either argon or nitrogen. Ac…

Broadband lasers have been suggested as a useful tool to suppress laser-plasma instabilities. However, this study shows that in the kinetic inflation regime broadband lasers are ineffective in suppressing backward stimulated Raman scattering (SRS). The role of electron trapping is pivotal in the persistence of SRS despite the increased laser bandwidth.

Electromagnetic showers developing from the collision of an ultraintense laser pulse with a beam of high-energy electrons or photons are investigated under conditions relevant to future experiments on multipetawatt laser facilities. A semianalytical model is derived that predicts the shower multipli…

In traditional indirect-drive double-shell inertial confinement fusion, high-energy x-ray preheat has always been identified as a major source of degrading implosion performance. However, a significant increase of the neutron yield is observed in ignition-like double-shell implosion experiments perf…

A theoretical model of stimulated Brillouin scattering (SBS) developed by a broadband laser in inhomogeneous plasmas is proposed and further investigated through a series of numerical simulations using the low-coherence laser model of the Kunwu facility. Polychromatic beamlets are coupled to develop…
