Postdoctoral position in attosecond physics - Hiring in process/Finished, not possible to apply

Description of the workplace

The Department of Atomic Physics at the Department of Physics, Lund University, has a staff of approximately 50 researchers, including visiting researchers and doctoral students. The research at the department is primarily based on the use of lasers, ranging from diode lasers to terawatt lasers at the High-Power Laser Laboratory. The research areas include the interaction between intense laser fields and matter, attosecond physics, quantum information, solid-state X-ray spectroscopy, laser applications in medicine and biology, as well as industrial applications. More information is available at www.atomic.physics.lu.se.

Subject description

The positions are linked to the attosecond group at the department. The group's research includes ultrafast optics and lasers, generation of attosecond pulses and applications of these to the study of ultrafast phenomena in various systems.

We are looking for one to three postdocs to develop attosecond pulse sources and to study dynamic processes in atoms and molecules using electron spectrometers. A position is linked to the research activity towards quantum metrology where the quantum properties of photoelectrons are measured. The second position focuses on the optimization of the generation of attosecond pulses for applications in the high-industrial sector. The third position involves the development of ultra-short pulse technology in the SWIR (short-wavelength infrared) spectral range.

Work duties

The main duties involved in a post-doctoral position is to conduct research. Teaching may also be included, but up to no more than 20% of working hours. The position includes the opportunity for three weeks of training in higher education teaching and learning. The purpose of the position is to develop the independence as a researcher and to create the opportunity of further development.

The postdoctoral positions are proposed around one of the following projects:

1. Ultrafast quantum physics. The project consists of studying the quantum state of a photoelectron created by absorption of attosecond light pulses. This includes the development of methods for measurements of the electron's coherence properties. The project, which lies on the border between attosecond physics and quantum information, includes theory and experiment.
2. Harmonic generation with industrial ytterbium laser sources for applications in semiconductor metrology and imaging. The project includes the development, optimization, and characterization of a laser-driven source for generating XUV pulses. It also includes phase and intensity modulation of the beam using spatial light modulators (SLMs) and pulse shaping in the time and frequency domains.
3. Development of a laser in the SWIR area and applications. The goal is to continue the development of a short-pulse laser system in the infrared spectral range at 1.8 um and to explore applications, especially the generation of attosecond pulses with high photon energy and time-resolved X-ray photoelectron spectroscopy.

The tasks include:

• Operation and development of a femtosecond laser system,
• Generation of attosecond pulses by harmonic generation in a gas,
• Explore applications in atoms or molecules in gas phase.

Duties also include supervision of master and doctoral students.

Qualification requirements

Appointment to a post-doctoral position requires that the applicant has a PhD, or an international degree deemed equivalent to a PhD, within the subject of the position. The certificate proving the qualification requirement is met, must be received before the employment decision is made. Priority will be given to candidates who have graduated no more than three years ago before the last day for application. Under special circumstances, the doctoral degree can have been completed earlier.

Additional requirements:

• Very good oral and written proficiency in English.
• Experience in ultrafast optics and/or practical experience with femtosecond lasers and/or harmonic generation in gas and/or pulse shaping and/or photoelectron spectroscopy,
• Works well in a group.

Assessment criteria

This is a career development position primarily focused on research. The position is intended as an initial step in a career, and the assessment of the applicants will primarily be based on their research qualifications and potential as researchers. Particular emphasis will be placed on research skills within the subject.

For appointments to a post-doctoral position, the following shall form the assessment criteria:

• A good ability to develop and conduct high quality research.
• Teaching skills.

Other qualifications:

• Experience with femtosecond lasers and ultrafast optics
• Experience in harmonic generation and attosecond physics
• Experience with photoelectron spectroscopy
• Other skills, e.g. instrument programming, data analysis, vacuum technology, mechanical design

Consideration will also be given to how the applicant’s experience and skills complement and strengthen ongoing research within the department, and how they stand to contribute to its future development.
