Missions

Topological states of matter show universal features across materials, like gapless boundary states, with unprecedented robustness to disorder. These properties hold the key to robust quantum technologies: quantum computation, spintronics, or thermo-electric sensors are important examples. Hence, discovering new topological materials and phases is a key contemporary challenge. Using crystal symmetry, around 50% of all non-magnetic crystals were recently predicted to be in a topological phase, and similar numbers are expected for magnetic materials. None of these materials is amorphous because these, by definition, lack long-range atomic order. This is a remarkable absence because amorphous matter can outperform ordinary crystals fundamentally and technologically. The above suggests that amorphous solids are the largest overlooked pool of affordable materials with potential for discovering topological phases with new, superior and controlable properties, a central goal of modern condensed matter. However, this pool remains inaccessible, and the two communities studying amor- phous matter remain largely disconnected.

The main goal of the project is to establishing novel computational ways to predict new amorphous topological insulators and metals.

Activities

- Simulation of realistic amorphous lattices using state-of-the-art techniques, such as first-principles molecular dynamics.
- Tight-binding modelling of amorphous topological matter.
- Conceiving, writing and disseminating scientific publications related to the topic of amorphous topological matter.
- Mentoring, and collaboration with other group members
- Participation in group meetings and the scientific life of the institute.

Skills

Priority will be given to candidates familiar with numerical methods to generate realistic amorphous structures, for example, using first-principle molecular dynamics. Experience with the simulation of topological phases of matter using first principle calculations will be considered favorably. Candidates with strong experience in the interplay between disorder, superconductivity and topology will also be considered.

The applicant will be expected to actively participate in the group dynamics, act as an active mentor of younger generations of scientists, and publish their research in peer-reviewed journals.

Work Context

The Institut NÉEL is a CNRS unit (UPR 2940) under agreement with the University Grenoble Alpes. It is one of the largest French national research institutes for fundamental research in condensed matter physics enriched by interdisciplinary activities at the interfaces with chemistry, engineering and biology. It consists of 450 employees, including 175 researchers.
It is located in Grenoble, in the heart of a unique scientific, industrial and cultural environment, right next to the French Alpes.

The successful applicant will join the "Condensed matter theory" team. He/she
will work in the group of Adolfo G. Grushin, establishing numerical methods to generate realistic amorphous lattices, calculating topological invariants.

The applicant will benefit from collaborations with other group members in this area, ranging from numerical methods to field theoretical descriptions. Furthermore, the candidate will benefit from the interactions with local theorists and experimentalists in the rich scientific environment in Grenoble (CNRS, CEA, ESRF) who work in a wide range of topics. Additionally, a computational cluster for demanding calculations is available.

Possible collaboration and networking : : The project is embedded in a strong network of experimental and theoretical collaborations in Europe and USA, with ample funding to travel to conferences, visit collaborators.
