Framework Unites Attosecond Science and Semiconductor Physics for Quantum Studies

A new theoretical framework has been developed, integrating attosecond science with semiconductor physics to study quantum path interference. This framework focuses on reconstructing attosecond beating by interference of two-photon transitions (RABBIT) and time-resolved and angle-resolved photoemission spectroscopy (tr-ARPES). It investigates quantum path interference between Floquet and Volkov states and identifies a novel quantum path involving virtual excitation, advancing understanding in quantum phenomena.
