Measuring electron density and electromagnetic fields in low-density laser-driven plasmas using proton radiography
Joshua T. Y. Chu, Gianluca Gregori, Archie F. A. Bott +1
In this paper, we describe a novel technique for inferring electron density in laser plasmas from proton-radiography data. Proton radiography is primarily a diagnostic for imaging…
Assessing the Projector Augmented-Wave Method for Stopping Power Calculations
Bryn Lloyd, Dirk O. Gericke, Gilles Rodway-Gant +1
The stopping power of charged particles is investigated using time-dependent density functional theory (TDDFT). Such simulations are made possible by recent advances in computation…
Characterization of foam-filled hohlraums for inertial fusion experiments
Sam Iaquinta, Peter Amendt, Jose Milovich +8
On the path towards high-gain inertial confinement fusion ignition, foams are being considered to tamp the hohlraum wall-motion, and mitigate laser backscattering from Stimulated R…
Bounds on heavy axions with an X-ray free electron laser
Jack W. D. Halliday, Giacomo Marocco, Konstantin A. Beyer +18
We present new exclusion bounds obtained at the European X-ray Free Electron Laser facility (EuXFEL) on axion-like particles (ALPs) in the mass range 10^{-3} eV < m_a < 10^4 eV. Ou…
Speed of sound in methane under conditions of planetary interiors
Thomas G. White, Hannah Poole, Emma E. McBride +32
We present direct observations of acoustic waves in warm dense matter. We analyze wave-number- and energy-resolved x-ray spectra taken from warm dense methane created by laser heat…
Classical Larmor formula through the Unruh effect for uniformly accelerated electrons
Georgios Vacalis, Atsushi Higuchi, Robert Bingham +1
We investigate the connection between the classical Larmor formula and the quantum Unruh effect by computing the emitted power by a uniformly accelerated charged particle and its a…
Time-resolved fast turbulent dynamo in a laser plasma
A. F. A. Bott, P. Tzeferacos, L. Chen +25
Understanding magnetic-field generation and amplification in turbulent plasma is essential to account for observations of magnetic fields in the universe. A theoretical framework a…
Transport of high-energy charged particles through spatially-intermittent turbulent magnetic fields
L. E. Chen, A. F. A. Bott, P. Tzeferacos +22
Identifying the sources of the highest energy cosmic rays requires understanding how they are deflected by the stochastic, spatially intermittent intergalactic magnetic field. Here…
Proton imaging of stochastic magnetic fields
A. F. A. Bott, C. Graziani, P. Tzeferacos +4
Recent laser-plasma experiments report the existence of dynamically significant magnetic fields, whose statistical characterisation is essential for understanding the physical proc…
Axion driven cosmic magneto-genesis during the QCD crossover
Francesco Miniati, Gianluca Gregori, Brian Reville +1
We propose a mechanism for the generation of a magnetic field in the early universe during the QCD crossover assuming that dark matter is made of axions. Thermoelectric fields aris…
Laboratory evidence of dynamo amplification of magnetic fields in a turbulent plasma
P. Tzeferacos, A. Rigby, A. Bott +27
Magnetic fields are ubiquitous in the Universe. Extragalactic disks, halos and clusters have consistently been shown, via diffuse radio-synchrotron emission and Faraday rotation me…
Theory of Thomson scattering in inhomogeneous media
P. M. Kozlowski, B. J. B. Crowley, D. O. Gericke +2
Thomson scattering of laser light is one of the most fundamental diagnostics of plasma density, temperature and magnetic fields. It relies on the assumption that the properties in…
Laser-driven platform for generation and characterization of strong quasi-static magnetic fields
J. J. Santos, M. Bailly-Grandvaux, L. Giuffrida +31
Quasi-static magnetic-fields up to T are generated in the interaction of intense laser pulses (J, ns, W/cm) with capacitor-coil targets of differe…
Scaling of Magneto-Quantum-Radiative Hydrodynamic Equations: From Laser-produced Plasmas to Astrophysics
Joseph E. Cross, Brian Reville, Gianluca Gregori
We introduce here the equations of magneto-quantum-radiative hydrodynamics. By rewriting them in a dimensionless form, we obtain a set of parameters that describe scale-dependent r…
