    Ultra-High-Energy Cosmic Rays Accelerated by Magnetically Dominated Turbulence by Luca Comisso, Glennys R. Farrar, Marco S. Muzio

    Published 2024-01-01
    “…One promising mechanism of UHECR acceleration is magnetized turbulence. We demonstrate from first principles, using fully kinetic particle-in-cell simulations, that magnetically dominated turbulence accelerates particles on a short timescale, producing a power-law energy distribution with a rigidity-dependent, sharply defined cutoff well approximated by the form ${f}_{\mathrm{cut}}\left(E,{E}_{\mathrm{cut}}\right)={\rm{sech}} \left[{(E/{E}_{\mathrm{cut}})}^{2}\right]$ . …”

    The Half-Space Sommerfeld Problem of a Horizontal Dipole for Magnetic Media by Seil Sautbekov, Merey Sautbekova

    Published 2025-01-01
    “…A Hertz radiator’s Sommerfeld boundary value problem is considered for the case when its electric moment is directed horizontally relative to the plane interface between two media with different values of magnetic permeability. An integral representation of the exact expression for the Hertz potential, which generalizes the classical solution for non-magnetic media, both in cylindrical and spherical coordinate systems, is obtained. …”
