Covariant Cherenkov Radiation and its Friction Force
Will Price, Martin S. Formanek, Johann Rafelski
We derive the covariant generalization of the Frank-Tamm formula describing the Cherenkov radiation by a charged particle moving uniformly with a speed faster than the local speed…
Self-consistent strong screening applied to thermonuclear reactions
Christopher Grayson, Cheng Tao Yang, Martin Formanek +1
Self-consistent strong plasma screening around light nuclei is implemented in the Big Bang nucleosynthesis (BBN) epoch to determine the short-range screening potential, $eϕ(r)/T \g…
Fermi-Dirac Integrals in Degenerate Regimes: A Novel Asymptotic Expansion
Jeremiah Birrell, Martin Formanek, Andrew Steinmetz +2
We characterize in a novel manner the physical properties of the low temperature Fermi gas in the degenerate domain as a function of temperature and chemical potential. For the fir…
Electron-positron plasma in BBN: damped-dynamic screening
Christopher Grayson, Cheng Tao Yang, Martin Formanek +1
We characterize in detail the very dense plasma present during the Big-Bang Nucleosynthesis (BBN) and explore how it is perturbed electromagnetically by \lq\lq impuriti…
Signatures of vacuum birefringence in low-power flying focus pulses
Martin Formanek, John P. Palastro, Dillon Ramsey +2
Vacuum birefringence produces a differential phase between orthogonally polarized components of a weak electromagnetic probe in the presence of a strong electromagnetic field. Desp…

Exact solutions for the electromagnetic fields of a flying focus
D. Ramsey, A. Di Piazza, M. Formanek +10
The intensity peak of a "flying focus" travels at a programmable velocity over many Rayleigh ranges while maintaining a near-constant profile. Assessing the extent to which these f…
Dynamic Magnetic Response of Quark-Gluon Plasma to Electromagnetic Fields

We investigate the strong acceleration properties of the radiation reaction force and identify a new and promising limiting acceleration feature in the Eliezer-Ford-O'Connell model…
Nonlinear Thomson scattering with ponderomotive control
D. Ramsey, B. Malaca, A. Di Piazza +7
In nonlinear Thomson scattering, a relativistic electron reflects and re-radiates the photons of a laser pulse, converting optical light to x rays or beyond. While this extreme fre…
