Birefringence in thermally anisotropic relativistic plasmas and its impact on laser-plasma interactions
A. Arefiev, D. Stark, T. Toncian +1
One of the paradigm-shifting phenomena triggered in laser-plasma interactions at relativistic intensities is the so-called relativistic transparency. As the electrons become heated…
A semi-implicit, energy- and charge-conserving particle-in-cell algorithm for the relativistic Vlasov-Maxwell equations
Guangye Chen, Luis Chacón, Lin Yin +3
Conventional explicit electromagnetic particle-in-cell (PIC) algorithms do not conserve discrete energy exactly. Time-centered fully implicit PIC algorithms can conserve discrete e…
A 1D fluid model of the Centaurus A jet
Sarka Wykes, Bradford T. Snios, Paul E. J. Nulsen +11
We implement a steady, one-dimensional flow model for the X-ray jet of Centaurus A in which entrainment of stellar mass loss is the primary cause of dissipation. Using over 260 ks…
Self-aligning concave relativistic plasma mirror with adjustable focus
Hai-En Tsai, Alexey V. Arefiev, Joseph M. Shaw +4
We report an experimental-computational study of the optical properties of plasma mirrors (PMs) at the incident laser frequency when irradiated directly at relativistic intensity (…
Beltrami state in black-hole accretion disk: A magnetofluid approach
Chinmoy Bhattacharjee, Rupam Das, David J. Stark +1
Using the magnetofluid unification framework, we show that the accretion disk plasma (embedded in the background geometry of a blackhole) can relax to a class of states known as th…
A Relativistic Plasma Polarizer: Impact of Temperature Anisotropy on Relativistic Transparency
David J. Stark, Chinmoy Bhattacharjee, Alexey V. Arefiev +2
3D particle-in-cell simulations demonstrate that the enhanced transparency of a relativistically hot plasma is sensitive to how the energy is partitioned between different degrees…
