Abstract:
Attosecond transient absorption (ATA) studies provide a way to push our understanding of the energy transfer between electromagnetic fields and matter to the sub femtosecond time scale. ATA is an all-optical attosecond metrology that complements methods based on the measurement of charged particles, such as attosecond streaking and electron interferometry.

In this talk I will review the basics of ATA and summarize recent results in this fast growing field. I will discuss calculations from our attosecond theory group on ATA in laser-dressed atoms that highlight the extent to which attosecond dynamics can be extracted from these measurements.
