Abstract

Intriguing physics and chemistry problems abound in the pursuit of attosecond science, as such measurements push the boundaries of fundamental electron dynamics timescales. The x-ray transitions accessed by attosecond pulses are responsive to charge, chemical oxidation state, and electronic environment, and they exhibit sensitive shifts even with vibrational excitation. An introduction to attosecond measurements is presented, with a basic goal to reveal new dynamical timescales. Investigations involve the development of methods to explore coherent electronic superpositions and charge migration in molecules and to determine how fast a semiconductor band gap responds to the injection of carriers.
