Researcher in condensed matter theory with a focus on spectroscopy, entanglement and quantum matter

Description of the workplace
The division of mathematical physics spans both the faculties of natural science and engineering science (LTH), and it is a part of the department of physics. Research is conducted primarily in the fields of quantum many-body systems, which includes theoretical research in nuclear physics, nanometer physics, quantum information, atomic physics, and modeling of materials, with several collaborations internationally and within Lund University.

Subject description
Entanglement, an important manifestation of quantum mechanics, is considered crucial for quantum information technologies, but it is also fragile and challenging to maintain. The project aims to characterize the time evolution of entanglement in complex matter induced by ultrafast light pulses and studied by time-resolved photoelectron spectroscopy and microscopy. In particular, the project will focus on how entanglement decays in a system via decoherence mechanisms due to the environment. Examples of systems that will be considered are atoms adsorbed on surfaces, acceptor-donor complexes and topological magnetic structures in optical cavities.

Work duties
The main duty involved in this position is to conduct research, and the co-supervision of master's theses and doctoral students. Teaching may also be included, but up to no more than 10% of the working hours.

The research to conduct aims to explore (and gain insight into) general properties of entanglement dynamics in the context of ultrafast spectroscopy for different topologies of systems. To this end, the project will use advanced computational and theoretical methods to describe the many-body physics underlying the dynamics of entanglement, the processes involved in time-resolved spectroscopies and the decoherence mechanisms in quantum matter, notably atoms and molecules adsorbed on surfaces, acceptor-donor complexes and topological magnetic structures. The theoretical work in the project will be conducted locally and in collaboration with other international theoretical groups.

Qualification requirements

• A PhD in physics.
• Very good oral and written proficiency in English.

Additional requirements:

• Experience in theoretical and computational modelling of the electronic, entanglement, and magnetic properties of materials in and out of equilibrium, for example via equilibrium and non-equilibrium Green's functions, density functional theory, and tensor network methods.
• Experience in topological magnetic systems and nonlinear optical phenomena is considered positively.

 Assessment criteria and other qualifications

• Good ability to develop and conduct research of good quality.
• Ability to collaborate and work in a team.
• Ability to take personal responsibility for the progress of projects.
• Experience of publishing in scientific journals.

Consideration will also be given to good collaborative skills, drive and independence, and 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.
