Postdoctoral Researcher in Condensed Matter Theoretical Physics (Multi-Orbital Quantum Systems) Wrocław University of Science and Technology in Poland

This postdoctoral position at Wrocław University of Science and Technology offers an exciting opportunity to join the research group of Dr Jacek Herbrych, working on the NCN SONATA BIS 13 project entitled “Properties of low-dimensional quantum systems with charge, spin, and orbital degrees of freedom.” The project focuses on the theoretical investigation of multi-orbital quantum systems, exploring phenomena such as the orbital-selective Mott phase (OSMP), where competing interactions lead to selective electron localization on certain orbitals. These systems exhibit unique properties, including the coexistence of insulating and metallic bands, and their momentum-dependent features are studied using advanced spectroscopic techniques.

The research aims to advance the understanding of models with multiple competing energy scales, including the multi-orbital Hubbard model, generalized Kondo-Heisenberg model, spin-orbital model, and effective models with RKKY-like interactions. Theoretical analysis of these Hamiltonians will provide guidance for experimentalists and crystal growers, potentially leading to the discovery of new low-dimensional compounds with exotic quantum properties.

The successful candidate will contribute to the development and application of analytical and numerical methods for strongly correlated quantum systems. Experience with quantum mechanics, solid state physics, lattice models, many-body physics, and state-of-the-art diagonalization and MPS-based techniques is essential. Programming skills in C/C++, Fortran, Python, or Julia are required, along with proficiency in scientific writing and presentation (including LaTeX). Candidates must be fluent in English and hold a PhD in physics or a closely related discipline. Peer-reviewed publications in relevant fields are expected.

The position is fully funded for 24 months through a full employment contract. The application process involves submitting a CV, motivational letter, and two reference letters to Dr Jacek Herbrych via email. Consent for personal data processing is required, and shortlisted candidates will be invited to an interview. PhD diplomas from outside the EU must be nostrified, which may delay employment. The recruitment process follows National Science Center (NCN) regulations, and the committee reserves the right not to award the position if criteria are unmet.
