High-order correlations and ultrafast Wigner negativities in bright-squeezed-vacuum-driven high-harmonic generation
High-harmonic generation (HHG) is a prototypical strong-field process in which intense light drives matter to emit radiation at integer multiples of the driving frequency. Extending HHG into the quantum-optical regime offers new opportunities to probe and control strongly nonlinear light-matter interactions using noncl...
