Abstract: Particle accelerators driven by laser-generated terahertz (THz) pulses promise unprecedented control over the energy–time phase space of particle bunches compared with conventional radiofrequency technology. Here we demonstrate acceleration of a relativistic electron beam in a… read more here.

DOI: 10.1093/mnras/stx2485
Abstract: We examine limits to the energy to which cosmic rays can be accelerated by relativistic shocks, showing that acceleration of light ions as high as 100 EeV is unlikely. The implication of our estimates is… read more here.

DOI: 10.1103/physrevd.102.023003
Abstract: We discuss the physics of stochastic particle acceleration in relativistic MHD turbulence, combining numerical simulations of test-particle acceleration in synthetic wave turbulence spectra with detailed analytical estimates. In particular, we study particle acceleration in wave-like… read more here.

DOI: 10.1103/physrevlett.121.255101
Abstract: Due to its ubiquitous presence, turbulence is often invoked to explain the origin of nonthermal particles in astrophysical sources of high-energy emission. With particle-in-cell simulations, we study decaying turbulence in magnetically dominated (or, equivalently, "relativistic")… read more here.
