Collective plasma effects of electron-positron pairs in beam-driven QED cascades
Kenan Qu, Sebastian Meuren, Nathaniel J. Fisch
Understanding the interplay of strong-field QED and collective plasma effects is important for explaining extreme astrophysical environments like magnetars. It has been shown that…
MP3 White Paper 2021 -- Research Opportunities Enabled by Co-locating Multi-Petawatt Lasers with Dense Ultra-Relativistic Electron Beams
Sebastian Meuren, David A. Reis, Roger Blandford +11
Novel emergent phenomena are expected to occur under conditions exceeding the QED critical electric field, where the vacuum becomes unstable to electron-positron pair production. T…
Generating optical supercontinuum and frequency comb in tenuous plasmas
Kenan Qu, Nathaniel J. Fisch
There are several mechanisms by which the frequency spectrum of a laser broadens when it propagates at near-relativistic-intensity in tenuous plasma. Focusing on one dimensional ef…
Modulation-Slippage Tradeoff in Resonant Four-Wave Upconversion
Alec Griffith, Kenan Qu, Nathaniel J. Fisch
Following up on a proposal to use four-wave mixing in an underdense plasma at mildly relativistic laser intensities to produce vastly more energetic x-ray pulses [V. M. Malkin and…
