Distinguishing between squeezed light and coherent state mixture drivers in above threshold ionization

Abstract

Recent theoretical and experimental studies showed that high harmonic generation (HHG) and above threshold ionization (ATI) can be driven by non-classical light, e.g. bright squeezed vacuum. However, all the theoretical studies analyzed these processes by incoherent summation of semi-classical contributions. This raises a pivotal question in the emerging field of strong-light quantum optics: are there quantum signatures in these experiments that cannot be obtained by driven these processes with a mixture of coherent states? I will address this question in my talk and present a proposed ATI experiment that distinguishes between squeezed driver and coherent state mixture driver.
