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 first 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]
We first met him on July (2024) in Garching bei München for the Multiphotonics (2024) workshop. He is a 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.
