Doctoral Position in circularly polarized attosecond pulses and chiral charge migration

Contribute to the implementation and operation of an attosecond beamline based on a CEP-stabilized, few-cycle 100 kHz Yb-fibre laser and high-harmonic generation. Generate circularly polarized attosecond pulse trains and isolated attosecond pulses, and characterize their temporal structure and complete polarization state. Integrate the isolated attosecond and single-cycle optical pulses into a reaction microscope and perform three-dimensional electron-ion coincidence measurements. Investigate chirality-sensitive charge migration and charge transfer in isolated molecules and microhydrated molecular clusters. Work closely with the Attochirality team, including laser scientists, engineers and theory collaborators. Present results at international conferences and publish them in peer-reviewed journals; contribute to the scientific life and teaching activities of the group.

The Ultrafast Spectroscopy and Attosecond Science group at the Laboratory of Physical Chemistry, Department of Chemistry and Applied Biosciences, ETH Zurich develops experimental methods for measuring and controlling electronic dynamics in molecules on attosecond time scales, during chemical reactions and in the liquid phase.
