Photon Acceleration in Magnetized Plasma: A Mechanism for Fast Radio Bursts

Sergei V. Bulanov, Gabriele Maria Grittani, Marcel Lamac +7

We propose a mechanism for fast radio bursts based on photon acceleration by relativistic shocks propagating through highly magnetized electron--positron plasmas, as expected in ma…

An axion framework for Particle-in-Cell codes with Monte-Carlo sampling: emission, absorption, and detailed balance in plasmas

Miles Radford, Ahmed Alsulami, Bertrand Martinez +5

We present an extension of the OSIRIS particle-in-cell (PIC) code that introduces an axion macroparticle species and three axion-production channels commonly used in thermal-plasma…

Probing keV mass QCD axions with the SACLA X-ray free electron laser

Charles Heaton, Jack W. D. Halliday, Taito Osaka +12

Axions are hypothetical particles, proposed to account for the invariance of CP symmetry in quantum chromodynamics. While axions and axion-like-particles are well-motivated by stri…

Proposal to use laser-accelerated electrons to probe the axion-electron coupling

Georgios Vacalis, Atsushi Higuchi, Robert Bingham +1

The axion is a hypothetical particle associated with a possible solution to the strong CP problem and is a leading candidate for dark matter. In this paper we investigate the emiss…

Laboratory observation of collective beam-plasma instabilities in a relativistic pair jet

J W D Halliday, C D Arrowsmith, A M Goillot +37

We report on a measurement of collective behavior in a relativistic electron-positron pair plasma produced in the laboratory. Using the Fireball platform at CERN's HiRadMat facilit…

Photon Accelerator in Magnetized Electron-Ion Plasma

Sergei Bulanov, Stepan Bulanov, Timur Esirkepov +6

Strong magnetic fields and plasmas are intrinsically linked in both terrestrial laboratory experiments and in space phenomena. One of the most profound consequences of that is the…
