Space-time structured plasma waves
J. P. Palastro, K. G. Miller, R. K. Follett +4
Electrostatic waves play a critical role in nearly every branch of plasma physics from fusion to advanced accelerators, to astro, solar, and ionospheric physics. The properties of…
Positron generation and acceleration in a self-organized photon collider enabled by an ultra-intense laser pulse
K. Sugimoto, Y. He, N. Iwata +4
We discovered a simple regime where a near-critical plasma irradiated by a laser of experimentally available intensity can self-organize to produce positrons and accelerate them to…
Efficient generation of axial magnetic field by multiple laser beams with twisted pointing directions
Yin Shi, Alexey Arefiev, Jue Xuan Hao +1
Strong laser-driven magnetic fields are crucial for high-energy-density physics and laboratory astrophysics research, but generation of axial multi-kT fields remains a challenge. T…
Enhanced proton acceleration in an applied longitudinal magnetic field
Alexey Arefiev, Toma Toncian, Gennady Fiksel
Using two-dimensional particle-in-cell simulations, we examine how an externally applied strong magnetic impacts proton acceleration in laser-irradiated solid-density targets. We f…
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…
Temporal resolution criterion for correctly simulating relativistic electron motion in a high-intensity laser field
Alexey V. Arefiev, Ginevra E. Cochran, Douglass W. Schumacher +2
Particle-in-cell codes are now standard tools for studying ultra-intense laser-plasma interactions. Motivated by direct laser acceleration of electrons in sub-critical plasmas, we…
