Distinguishing between classical (coherent state mixtures) and quantum drivers in strong-field experiments"

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 semiclassical 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.
