The motion of laser-driven electrons quivers with an average energy termed pondermotive energy. We explore electron dynamics driven by bright squeezed vacuum (BSV)
finding that BSV induces width oscillations
akin to electron quivering in laser light
with an equivalent ponderomotive energy. We identify closed and open trajectories of the electronic width that are associated with high harmonic generation and above-threshold ionization
respectively
similarly to trajectories of the electron position when its motion is driven by coherent light. In the case of bound electrons
the width oscillations may lead to ionization with noisy sub-cycle structure. Our results are foundational for strong-field and free-electron quantum optics
as they shed light on ionization
high harmonic generation
and nonlinear Compton scattering in BSV.
