Attosecond control and measurement of chiral photoionization dynamics.

ABSTRACT: Many chirality-sensitive light-matter interactions are governed by chiral electron dynamics. Therefore, the development of advanced technologies making use of chiral phenomena would critically benefit from measuring and controlling chiral electron dynamics on their natural attosecond timescales. Such endeavours have so far been hampered by the lack of characterized circularly polarized attosecond pulses, an obstacle that has recently been overcome^1,2. Here we introduce chiroptical spectroscopy with attosecond pulses and demonstrate attosecond coherent control over photoelectron circular dichroism (PECD)^3,4, as well as the measurement of chiral asymmetries in the forward-backward and angle-resolved photoionization delays of chiral molecules. We show that co-rotating at
