Attosecond metrology in circular polarization*

Many chirality-sensitive light-matter interactions are governed by chiral electron dynamics. Therefore,

the development of advanced technologies harnessing chiral phenomena would critically benefit from

measuring and controlling chiral electron dynamics on their natural attosecond time scales. Such

endeavors have so far been hampered by the lack of characterized circularly polarized attosecond pulses,

an obstacle that has recently been overcome. In this presentation, I will introduce chiroptical spectroscopy with

attosecond pulses and demonstrate attosecond coherent control over photoelectron circular dichroism

(PECD), as well as the measurement of chiral asymmetries in the photoionization

delays of chiral molecules.
