In our laboratories at ETH Zurich in the group of Prof. Ursula Keller we conduct coincidence pump probe experiments with attosecond time-resolution on atomic and molecular targets combining a compact XUV attosecond beamline which generates trains and isolated attosecond pulses with a 3D momentum imaging spectrometer (COLTRIMS or Reaction Microscope).

In the previous years we could address several fundamental questions such as:

How fast can an electron tunnel through a potential barrier [1, 2]?
How fast are electrons released in sequential double ionization triggered by multi-photon absorption [3]?
What’s the impact of resonances on photoemission time delays [4, 5]?
Is the photoemission time delay of the photoemitted electrons showing any angular dependence [6]?
What’s happening in molecules? Do the nuclear dynamics or the complex 3D Coulomb potential affect the ionization dynamics [7, 8]?

Many of these questions will undoubtedly spark more questions – revealing deeper and more detailed insights into the dynamics of some of the most fundamental and relevant optoelectronic processes. Tunnelling, charge transfer, and energy transport all play key roles in electronics, energy conversion, chemical and biological reactions, and fundamental processes important for improved information, health, and energy technologies.

ETHZ - PhD position in Attosecond molecular electron dynamics

Your job

Ongoing projects are investigating new applications of our unique setup to perform coincidence pump-probe experiments on single-photon ionization of atomic and molecular targets and molecular dissociation dynamics. This PhD project will scale our attosecond-coincidence detection technique to molecules with increasing complexity, in particular we will address photoionization processes where multi-particles coincidence detection is required, meaning more than one ion and one electron.

The candidate should be interested in exploring new frontiers in fundamental dynamics using cutting-edge laser and detector techniques as mentioned above. He/she should be able to work with an enthusiasm for experimental research in an international team environment.

Your profile

We are seeking an outstanding and highly motivated candidate with a Master’s or equivalent degree in physics. Experience in any of our research topics mentioned above is advantageous but not necessary. Written and oral communication skills in English are required. Applicants are encouraged to send a curriculum vitae, a motivation letter, list of grades (Bachelor and Master), and provide names and contact information for at least two referees.
