Coherent axion electrodynamics in OSIRIS: a counter-propagating axion-photon parametric instability
Miles Radford, Pablo Bilbao, Thomas Grismayer +4
We present a coherent axion-electrodynamics extension of the OSIRIS particle-in-cell code and use it to identify and benchmark a parametric axion-photon instability supported by tw…
Generative Diffusion Surrogates with Analytical Variance Schedule
Patrick Reichherzer, Gianluca Gregori, David N. Hosking +1
Stochastic transport describes physical systems in which an initially structured distribution spreads under unresolved forcing, scattering, or heterogeneous media. Useful surrogate…
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…
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…
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…
Emission of pairs of Minkowski photons through the lens of the Unruh effect
Juan V. O. Pêgas, Robert Bingham, Gianluca Gregori +1
We discuss the emission of pairs of photons by charges with generic worldlines in the Minkowski vacuum from the viewpoint of inertial observers and interpret them from the perspect…
Suppression of pair beam instabilities in a laboratory analogue of blazar pair cascades
Charles D. Arrowsmith, Francesco Miniati, Pablo J. Bilbao +28
The generation of dense electron-positron pair beams in the laboratory can enable direct tests of theoretical models of -ray bursts and active galactic nuclei. We have successfu…
An Online Data Analysis Framework for Small-Scale Physics Experiments
Hayden Ramm, Pascal Simon, Paraskevi Alexaki +11
A robust and flexible architecture capable of providing real-time analysis on diagnostic data is of crucial importance to physics experiments. In this paper, we present such an onl…
Larmor radiation as a witness to the Unruh effect
Atsushi Higuchi, George E. A. Matsas, Daniel A. T. Vanzella +5
We discuss the emission of radiation from general sources in quantum scalar, electromagnetic and gravitational fields using the Rindler coordinate frame, which is suitable for a un…
