Postdoctoral positions in many-body quantum theory for superconductivity, topology and quantum geometry at Aalto University

The Quantum Dynamics (QD) Group at the Department of Applied Physics is looking for two postdoctoral researchers to work on quantum many-body theory, in particular on the connection between quantum geometry, topology and superfluidity/superconductivity, in bosonic and fermionic systems. The position is part of the current programs of the group funded by Academy of Finland. The QD research group is located on the university campus near Helsinki and offers a motivating and state-of-the-art research environment.

‍Research topics and major responsibilities

Your research will be directed towards understanding the significance of quantum geometry and topology on the macroscopic quantum state of bosonic and fermionic many-body systems. The emphasis will be on superfluidity, superconductivity and Bose-Einstein condensation, ordered phases competing with these, and the corresponding normal state properties. Your main responsibility is to study superconductivity and related phases in fermionic systems, in particular in the context of ultracold gases and moire materials such as twisted bilayer graphene, and to explore the effect of quantum geometry on superfluidity in bosonic systems with a connection to the experiments done in the group. Since two postdocs will be hired, you can specialize to only a subset of these topics according to your interests. The group has a powerful dynamical mean-field theory (DMFT) code, and it is desired that at least one of the postdocs would utilize it in the research. Background for the work is given by our discovery of the connection between quantum geometry and superconductivity (Nature Communications 2015, https://www.nature.com/articles/ncomms9944) which we have recently shown to be relevant in the context of twisted bilayer graphene superconductivity (https://arxiv.org/abs/1906.06313). Concerning our experiments, see the recent observation of Bose-Einstein condensation in plasmonic lattices (Nature Physics 2018, https://www.nature.com/articles/s41567-018-0109-9).
