Journal ArticleDOI
Amplification and generation of ultra-intense twisted laser pulses via stimulated Raman scattering
Jorge Vieira,Raoul Trines,Eduardo Paulo Alves,Ricardo Fonseca,Ricardo Fonseca,José Tito Mendonça,Robert Bingham,Peter Norreys,Peter Norreys,Luis O. Silva +9 more
TL;DR: Th theoretically and with ab initio three-dimensional particle-in-cell simulations that stimulated Raman backscattering can generate and amplify twisted lasers to petawatt intensities in plasmas may open new research directions in nonlinear optics and high–energy-density science, compact plasma-based accelerators and light sources.
Journal ArticleDOI
Efficient Nonthermal Particle Acceleration by the Kink Instability in Relativistic Jets.
TL;DR: A new acceleration mechanism associated with the development of the helical kink instability in relativistic jets, which leads to the efficient conversion of the jet's magnetic energy into nonthermal particles, and offers a viable means of accelerating ultrahigh-energy cosmic rays to 10^{20} eV.
Journal ArticleDOI
Large-scale magnetic field generation via the kinetic Kelvin-Helmholtz instability in unmagnetized scenarios
Eduardo Paulo Alves,Thomas Grismayer,Samuel Martins,Frederico Fiuza,Ricardo Fonseca,Ricardo Fonseca,Luis O. Silva +6 more
TL;DR: In this paper, the collisionless Kelvin-Helmholtz instability (KHI) was used to generate a large-scale DC magnetic field, reaching thicknesses of a few tens of electron skin depths.
Journal ArticleDOI
High orbital angular momentum harmonic generation
Jorge Vieira,Raoul Trines,Eduardo Paulo Alves,Ricardo Fonseca,Ricardo Fonseca,José Tito Mendonça,Robert Bingham,Peter Norreys,Peter Norreys,Luis O. Silva +9 more
TL;DR: A high orbital angular momentum harmonics generation and amplification mechanism that manipulates the OAM independently of any other laser property, by preserving the initial laser wavelength, through stimulated Raman backscattering in a plasma is identified and explored.
Journal ArticleDOI
dc-Magnetic-Field Generation in Unmagnetized Shear Flows
TL;DR: The generation of dc magnetic fields in unmagnetized electron-ion shear flows is shown to be associated to either initial thermal effects or the onset of electron-scale shear instabilities, in particular the cold Kelvin-Helmholtz instability.
