Single-Shot Intensity-Correlation Diffractive X-ray Imaging of ICF Plasmas
Kenan Qu, Daniel Bhatti, Nathaniel J. Fisch
X-ray radiography of inertial confinement fusion plasmas is currently limited to several-micron resolution by geometric blur, diffraction, and photon-throughput tradeoffs. We propo…
Detecting Solenoidal Plasma Turbulence via Laser Polarization Rotation
Kenan Qu, Nathaniel J. Fisch
Recent theoretical studies suggest that solenoidal turbulence can significantly enhance fusion reactivity, yet no standard diagnostic exists to directly measure these solenoidal fl…
Ultra-strong Quantum Squeezing Mediated by Plasma Waves
Kenan Qu, Nathaniel J. Fisch
Quantum squeezed states enable precision measurements beyond the standard quantum limit, but conventional solid-state media fundamentally limit pump intensities to the ionization t…
Producing entangled photon pairs and quantum squeezed states in plasmas
Kenan Qu, Nathaniel J. Fisch
Plasma is capable of mediating the conversion of two pump photons into two different photons through a relativistic four-wave mixing nonlinearity. Spontaneously created photon pair…
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…
