Electron-correlation induced nonclassicallity of light from high-harmonic generation

Christian Saugbjerg Lange, Thomas Hansen, Lars Bojer Madsen

We study the effect of electron-electron correlations on the quantum state of the light emitted from high-harmonic generation (HHG). The quantum state of the emitted light is obtai…
