Description of the workplace

The research at the Division of Atomic Physics is centered on different applications of optics and lasers, including atomic and molecular physics with ultrashort light pulses, high-intensity laser-plasma physics, quantum information, and biophotonics. The Division operates the High-Power Laser Facility, including several advanced femtosecond laser systems, and collaborates with several free-electron laser facilities. It is a central part of a major interdisciplinary research environment within Lund University, the Lund Laser Centre, LLC. The division is also heavily involved in undergraduate education, especially within the Photonics program.

Being a doctoral student

As a doctoral student, you are both admitted as a student and employed at Lund University.

As a doctoral student, you will be trained in a scientific approach. In short, you will be trained to think critically and analytically, to solve problems independently using the right methods, and to develop an awareness of research ethics. In addition, you will have the opportunity to work on projects, to develop your leadership and pedagogical skills. Throughout your studies, you will be guided by supervisors. Doctoral studies end with a thesis and a doctoral degree.

Subject and project description

A major research area of the division of Atomic Physics is the generation and application of extremely short light pulses in the attosecond and extreme-ultraviolet regimes. The activities span ultrafast laser technology and extreme nonlinear optics, as well as studies of electron dynamics in atoms and molecules using attosecond light pulses. The division of Atomic Physics is now looking for (at least) two PhD students for the projects described below.

The first project is called: Ultrafast quantum metrology with photoelectrons. The project is based on a novel photoelectron quantum state tomography scheme developed in the group, combining attosecond pulse trains with spectrally tailored femtosecond infrared pulses. The goals of the project are (1) to investigate, using this method, how the quantum state of photoelectrons emitted from atoms and small molecules is influenced by the quantum state of the ionizing light and the properties of the target, and (2) to reconstruct the ultrafast entanglement and decoherence dynamics in the system. The project is mostly experimental but it can also have a theoretical component. The project might also include experiments at free electron laser facilities and/or at other laboratories in collaborating universities.

The second project is called Manipulation of ultrashort laser pulses from an industrial ytterbium laser for high-order harmonic generation and photoemission electron microscopy of nanostructured samples. The project’s goals, based on a unique industrial laser platform, are (1) to control the generated XUV light by shaping the driving laser field spectrally, spatially, and temporally using ultrafast nonlinear optics, and (2) to explore phase-matching regimes, design innovative gas targets and laser-driven generation geometries to increase XUV yield. Successful achievement of these goals promises to revolutionize XUV light generation in research environments, contribute to a deeper understanding of high-harmonic generation, and provide important tools in materials science, with applications in photoemission electron microscopy.

The third project is called: Attosecond pump-probe spectroscopy of charge dynamics in molecules. The project is based at the intense attosecond beamline at the Lund High-Power Laser Facility, where intense attosecond pulse trains are available. The goal of the project is to generate intense, isolated attosecond pulses at this beamline and use them for pump-probe studies of attosecond charge dynamics in molecules and for the study of the dynamics of nonlinear processes in atoms. The project includes: (1) development, optimization, and characterization of the beamline for the generation of intense isolated attosecond pulses; (2) development and implementation of pump-probe measurement techniques based on photoelectron-photoion covariance imaging, and (3) experimental studies of charge dynamics and nonlinear processes. The project might also include complementary experiments at international free electron laser facilities.
