Professor Päivi Törmä (Aalto University) is looking for a highly motivated Postdoctoral Researcher to work on the theory of quantum geometry and superconductivity, related to the Simons Collaboration on New Frontiers of Superconductivity. The project will be done in close collaboration with Professor Tero Heikkilä (University of Jyväskylä). 

Your role and goals

The research will focus on new frontiers of quantum geometric superconductivity such as non-equilibrium and dynamical phenomena in flat bands and includes collaboration with experimentalists. The goal is to understand how supercurrent and dissipative currents behave in flat band systems and in presence of quantum geometry, under non-equilibrium conditions. We are expecting to discover novel fundamental behavior and phenomena, as well as give predictions for non-equilibrium experiments and new generation of superconducting devices. 

There are possibilities for research collaboration and extended visits to the following partners of the Simons Collaboration and their institutions: Andrei Bernevig (Princeton University), Kristjan Haule (Rutgers University), Miguel Marques (Ruhr University Bochum) and Andrew Millis (Columbia University and Flatiron Institute). There are also other postdoc positions available within the Simons Collaboration, see here. The research involves close collaboration with experimentalists of the SuperC collaboration, particularly Dmitri Efetov and Milan Allan (LMU Munich) and Pertti Hakonen (Aalto University).

We search for a Postdoctoral Researcher with strong analytical skills and experience in quantum many-body theory, preferably in the fields of superconductivity, quantum geometry, quantum transport and/or topological physics. Experience on linear response theory and Keldysh techniques is highly appreciated. Expertise on numerical methods such as dynamical mean-field theory, quantum Monte Carlo, exact diagonalization, density-functional theory, non-equilibrium methods and/or machine learning is an additional bonus.

The Quantum Dynamics group led by Päivi Törmä has pioneered the idea that quantum geometry and topology allows supercurrent and superconductivity in flat bands where non-interacting particles are localized (Peotta and Törmä, Nature Communications 6, 8944 (2015)). Recently these concepts have become relevant for instance in the context of flat band superconductivity in twisted bilayer graphene (Törmä, Peotta, Bernevig, Nature Reviews Physics 4, 528 (2022). Tero Heikkilä is a pioneer in flat band superconductivity, especially on the potential of this mechanism to increase the critical temperature (Phys. Rev. B 83, 220503(R) (2011) - High-temperature surface superconductivity in topological flat-band systems (aps.org)). He is also an expert in superconducting (nano)electronics and related non-equilibrium phenomena (Rev. Mod. Phys. 90, 041001 (2018) - Colloquium: Nonequilibrium effects in superconductors with a spin-splitting field (aps.org)).

Your experience and ambitions

We are looking for a bright and motivated Postdoctoral Researcher with an excellent record in the field of the position. Good command of English (both verbal and written) and demonstrated ability to disseminate scientific results are mandatory requirements for the position. Finnish language is not required. Applicants must be motivated to conduct research at the highest international level.

Postdoctoral Researchers must hold a PhD degree in a suitable field. Also, researchers that are finishing their PhD within a few months may apply.

What we offer
 
Your location will be Aalto University, Finland. You will visit University of Jyväskylä a few times per year. Extended visits of several weeks to the other institutions mentioned above are possible and will be arranged according to your wishes.

Aalto University follows the salary system of Finnish universities. The salary ranges for a postdoc from 4020€ to 4420€ per month, depending on previous experience, and the postdoc contracts will initially be made for 2 years.  The contract includes Aalto University occupational healthcare.

Place and infrastructure
 
You will join the QD group at Aalto University. The QD group explores quantum many-body physics theory, with focus on superconductivity, quantum geometry and topology, and also conducts nanophotonics experiments with Bose-Einstein condensation and topological physics themes. Computational facilities available for the project are outstanding, and completely free of charge. Aalto University has its own cluster, and the computational infrastructure and services of the national scientific computing centre CSC are available. For instance last year, their LUMI supercomputer ranked fifth in speed in the TOP500 list of supercomputers and is the fastest supercomputer in Europe.

For recent research outputs of the groups, please see Päivi Törmä’s entry at Google Scholar,
and Tero Heikkilä’s entry at Google Scholar.

Aalto University has six schools with nearly 13 000 students and 400 professors. It is the largest university in Finland focusing on education and research and technology, science, business, and arts. The QD group is located on the Otaniemi campus in Espoo (10 km from the city center of Helsinki), which is one of the largest hubs of high-tech in Northern Europe.
