Andreas Muller is a physicist at USF Tampa where he leads the solid state quantum optics lab. An expert of the Mollow triplet[1]) (he did his PhD with Glen Solomon), he is the first and still the only one to have measured the two-photon spectrum of resonance fluorescence.[2] He later extended his experimental characterizations in a series of heroic works (sometimes requiring weeks of data acquisition).[3][4][5] He currently investigates gas detectors and sensors from a quantum perspective.
We first met him on July (2024) in Garching bei München for the Multiphotonics (2024) workshop. He is fluent in French and German (Bavarian-born) and the sort of experimental genius whose exceptional skills are hidden in humility and wholesomeness.
I am sure that his work on two-photon spectra which has been largely ignored so far will eventually be recognized as a historical breakthrough, for being so ahead of time and with such stupendous quality. He is the first person to have observed the leapfrog processes and two-mode squeezing in resonance fluorescence, so early that it was even before all this was understood.
