Electron penetration heating in turbulent magnetic loops driven by nonrelativistic laser-plasma interaction
Zheng Gong, Sida Cao, Caleb Redshaw +1
Using particle-in-cell simulations to study nonrelativistic laser pulse propagation in a under-critical plasma, we identify a novel mechanism that occurs during the growth of turbu…
Phase-dependent magnetic coherence in the turbulent interstellar medium
Iryna S. Butsky, Caleb Redshaw, Minjie Lei +2
Magnetic fields permeate the multiphase interstellar medium (ISM), yet their phase-dependent structure remains poorly constrained by observations. Dust polarization and \ion{H}{1}…
Near-Unity-Efficiency Gas Gratings for Ultraviolet, Visible, and Infrared High-Power Lasers
Ke Ou, Harsha Rajesh, Sida Cao +13
Interfering deep ultraviolet (DUV) lasers can induce substantial density modulations in an ozone-doped gas flow via photochemical reactions, creating volume diffraction gratings. T…
Radiation reaction effects on particle dynamics in intense counterpropagating laser pulses
Caleb Redshaw, Matthew R. Edwards
In high-intensity laser-plasma interactions, particles can lose a substantial fraction of their energy by emitting radiation. Using particle-in-cell simulations, we study the impac…
Neutral gas phase distribution from HI morphology: phase separation with scattering spectra and variational autoencoders
Minjie Lei, S. E. Clark, Rudy Morel +4
Unraveling the multi-phase structure of the diffuse interstellar medium (ISM) as traced by neutral hydrogen (HI) is essential to understanding the lifecycle of the Milky Way. Howev…
Focusing Terawatt-Scale Lasers Using Holographic Gaseous Lenses
Devdigvijay Singh, Ke Ou, Sida Cao +13
The capabilities of the world's highest energy and peak-power pulsed lasers are limited by optical damage, and further advances in high-intensity laser science will require optics…
