Vacant job

Lund University was founded in 1666 and is consistently ranked among the world's leading universities. We have approximately 46,000 students and 8,500 employees in Lund, Helsingborg, and Malmö. We are united in our strive to understand, explain, and improve our world and the conditions of human life.

Description of the Department

The Division of Mathematical Physics is shared between the Faculty of Science and the Faculty of Engineering (LTH) and is part of the Department of Physics. Research is primarily conducted in the field of quantum many-body physics, encompassing theoretical nuclear structure physics, nano-physics, quantum information, atomic theory, and material modeling, with numerous collaborations both internationally and within Lund University.

The main focus of the research group where this position is located is quantum theory, specifically computational physics and the modeling of ultracold atomic quantum gases. National and international collaboration will be a natural part of the team's work, including regular on-site visits to our partners in Sweden and abroad.

Being a PhD Student

As a PhD student, you are both admitted as a student and employed by Lund University.

As a doctoral student, you are trained in a scientific approach. This can be briefly described as gaining practice in critical and analytical thinking, solving problems independently using appropriate methods, and developing an awareness of research ethics. Additionally, PhD students are given the opportunity to work on projects, develop leadership skills, and enhance their pedagogical abilities. Throughout your studies, you are guided by supervisors. The doctoral studies conclude with a dissertation and a doctoral degree.

Subject and Project Description

The PhD project focuses on investigating, describing, and modeling phenomena and properties of ultracold atomic and molecular quantum gases and liquids that can be described within the framework of many-body quantum physics, both theoretically and computationally. You are expected to work within theoretical many-particle quantum physics with an emphasis on numerical methodology. The focus lies on the development of new computational frameworks to describe the properties of ultracold atomic and molecular quantum systems with polar interactions, with a strong focus on the development of the multi-configuration time-dependent Hartree (MCTDH) method for bosons and fermions, as well as developing new methodologies to describe collective excitations in systems with stronger interactions. The work will involve both analytical developments and numerical implementations and simulations.

Responsibilities

You will primarily devote yourself to your doctoral education, which includes participation in research projects as well as doctoral education courses, seminars, and conferences.

Within this project, you will visit our partners, nationally and internationally, for joint work on research projects. The project focuses on investigating, describing, and modeling phenomena and properties of ultracold atomic and molecular quantum gases and liquids that can be described within the framework of many-body quantum physics. You are expected to work within theoretical many-particle quantum physics. The theoretical work will focus on theoretical modeling and understanding of new quantum optical systems of ultracold polar molecules. The work will involve both analytical calculations and numerical simulations.

The responsibilities include contributing to:

• developing, implementing, and optimizing a multi-configuration-based time-dependent Hartree description of bosonic and fermionic many-particle quantum systems.
• modeling work in collaboration with experiments.
• publications on research results obtained in the project.
• knowledge transfer regarding HPC and coding within the group, as well as responsibility for code maintenance and organizational issues concerning data security and storage.
• The responsibilities may also include participation in teaching and other departmental activities (max 20% of working time).
