Strong-Field QED and High Intensity Laser-Plasma Interaction
- Christopher Barty (University of California - Irvine)
Laser wakefield acceleration (LWFA) [1] and x-ray/gamma-ray generation based on LWFA [2] are emerging technologies that exhibit promising advancements in the production of compact, high-energy electron and photon sources. The advent of PW and multi-PW lasers [3–5] has facilitated the investigation of new regimes of LWFA and radiation generation. We recently conducted a LWFA experiment with...
Quantum field theory predicts the vacuum to exhibit a non-linear response to strong electro-magnetic fields [1]. This fundamental tenet has remained experimentally challenging and is yet to be tested in the laboratory [2]. Macroscopic electromagnetic fields available in the laboratory fulfill $\left\{ \left|\overrightarrow{E}\right|,c\left|\overrightarrow{B}\right|\right\} \ll E_{S}$, with...
Photon vortices caring orbital angular momentum (OAM) [1] with a wave function of Laguerre Gaussian (LG) wave or Bessel wave are one of the most interesting topics in various fields of physics. The interaction between a photon vortex and a material such nucleus may be different from that with standard photons because the photon vortex has non-zero orbital angular momentum parallel to the...
For the past two decades, intense lasers have supported new schemes for generating high-energy particle beams in university-scale laboratories. With the direct laser acceleration (DLA) method, the leading part of the laser pulse ionizes the target material and forms a positively charged ion plasma channel into which electrons are injected and accelerated. DLA has been realized over a wide...
