Postdoctoral Researcher in the area of Topological quantum fluids

Aalto University is a community of bold thinkers where science and art meet technology and business. We are committed to identifying and solving grand societal challenges and building an innovative future. Aalto has six schools with nearly 11 000 students and a staff of more than 4000, of which 400 are professors. Our main campus is located in Espoo, Finland. Diversity is part of who we are, and we actively work to ensure our community’s diversity and inclusiveness in the future as well. This is why we warmly encourage qualified candidates from all backgrounds to join our community.

The Department of Applied Physics is now looking for a

Postdoctoral Researcher in the area of Topological quantum fluids

We invite applications for a post-doctoral position to strengthen the experimental effort in the Rota group at the Department of Applied Physics. The Rota group is among world leaders in research on topological quantum matter realized by various superfluid phases of 3He. This family of materials, existing at ultra-low millikelvin temperatures, is unique in diversity of properties determined by topology. Topology is overreaching theme in modern condensed-matter physics which in particular elucidate how common features emerge in very different physical systems. This allows us to model in laboratory processes in early Universe, prototype future quantum devices based on topological materials or discover new phases of matter like time crystals.

Your role and goals

You will develop a new experimental technique: Either ultra-sensitive nuclear magnetic resonance spectrometer based on a quantum amplifier coupled to a microfabricated pick-up coil or a nanoelectromechanical oscillator immersed in 3He and possessing an engineered site to connect to topological objects living in the superfluid. You will then use this technique to address two separate problems: One is a fundamental question about interaction of fermionic matter of different types (massive or massless like Majorana or Weyl) with topological quantum vacuum, especially in the presence of the controlled disorder. One of the goals is to understand the relaxation of vacuum energy in early Universe (famous cosmological constant problem). This work is supported by ERC Advanced Grant “From Topological Matter to Relativistic Quantum Vacuum”.

You will also use your new technique to study current through Josephson junctions connecting superfluid volumes with different topology. The goal is to build knowledge needed for optimal design of future topological quantum devices where such junctions will be the key element. This work will proceed in cooperation with Royal Holloway University of London within EU-supported European Microkelvin Platform.

Your experience and ambitions

We are looking for a bright and motivated postdoc with a track record in experimental low-temperature (preferably sub-Kelvin) physics. Hands-on experience of nuclear magnetic resonance,  quantum amplifiers or MEMS/NEMS devices is an additional benefit. Familiarity with algorithmic processing of experimental data and building supporting numerical models using suitable environment (e.g. Matlab) is desirable. Good command of English (both verbal and written) and demonstrated ability to disseminate scientific results are mandatory. You must be motivated to conduct research at the highest international level with the aim at publishing high-impact articles.

What we offer

We offer an environment which stimulates scientific breakthroughs. We operate a world-wide unique experimental system which simultaneously can cool the samples to ultra-low temperatures and rotate them. This allows us together with you to design and perform experiments which could not be realized anywhere else. You will enjoy team work of experimentalists and theoreticians and strong international cooperation.

The fixed term contract is initially for two years. The annual workload of research and teaching staff at Aalto University is currently 1612 hours. Aalto University follows the salary system of Finnish universities. The salary for a Postdoctoral researcher is  between 3600€ and 4000€ per month, depending on previous experience. The contract includes Aalto University occupational healthcare.

The primary workplace will be the Otaniemi Campus at Aalto University.
