Fig. 3: Sub-cycle dynamics of bound electrons driven by BSV.

(a) illustration of a model Xe atom interacting with a squeezed vacuum field (b) populations of the ground and 1^st excited state as a function of time. The states undergo Rabi oscillations, while steadily depleting as a function of time due to ionization. c Electron wavefunction density in real space as a function of time \({\rho }_{x,{x}}^{\left(e\right)}\left(t\right)\) (d) time derivation of total continuum state populations, indicative of the ionization rate as a function of time. The ionization occurs in noisy bursts that are in phase with the squeezed vacuum noise
