NewsQuantum interference visibility spectroscopy in two-color photoemission – published in Phys. Rev. Lett.
When two-color femtosecond laser pulses interact with matter, electrons can be emitted through various excitation pathways involving different combinations of photons from the individual colors. Quantum interference between these pathways gives rise to a strong oscillation of the photoemitted electron current, experimentally characterized by its visibility (contrast). We investigate the visibility of the quantum pathway […]When two-color femtosecond laser pulses interact with matter, electrons can be emitted through various excitation pathways involving different combinations of photons from the individual colors.
