- Organisation/Company: Institute of Low Temperature and Structure Research Polish Academy of Sciences
Offer Description
The Institute of Low Temperature and Structural Research of the Polish Academy of Sciences in Wrocław announces a competition to fill the position of assistant professor (in Polish: adiunkt) at the ILTSR PAS in the Division of Low Temperature and Superconductivity, contractor of the research project entitled “Heat and Geometry: Investigating the Geometric-Phase Origin of the Phonon Thermal Hall Effect” (UMO-2025/59/B/ST3/00232).
The contract will be concluded on a full-time basis for the period of 12 months with the possibility of extension to (total) 42 months. The monthly remuneration under the contract will amount to approx. 13.300,00 PLN gross. Detailed employment conditions will be specified in the employment contract concluded between the employed person and the Director of INTiBS PAN. The person employed will be subject to the provisions of the Institute's applicable Remuneration Regulations and other relevant internal regulations.
Project description
The main objective of the project is to experimentally confirm the occurrence of the phonon thermal Hall effect (PTHE) in non-magnetic insulators and to identify the microscopic mechanisms responsible for its emergence. The thermal Hall effect manifests itself in the generation of a transverse temperature gradient under an applied magnetic field when a longitudinal heat current flows through a material. Although the effect was originally attributed to the Lorentz force acting on charged heat carriers, recent observations have demonstrated that it also occurs in systems in which heat transport is mediated exclusively by electrically neutral quasiparticles. Particularly surprising are reports of a large PTHE in simple non-magnetic crystals, which cannot be properly described by existing theoretical models. The hypothesis underlying the project is that the PTHE in non-magnetic insulators is a manifestation of a geometric phase acquired by phonons. We assume that its origin depends on the class of material: in ionic insulators, the dominant role is played by Lorentz forces acting on Born effective charges, whereas in covalent insulators, the effect may arise from the lattice Aharonov–Bohm effect. This mechanism, associated with the breakdown of the Born–Oppenheimer approximation, allows the magnetic field to interact with lattice vibrations through the electron cloud, imparting an additional Berry phase to phonons and affecting phonon–phonon scattering processes.
Tasks description
The responsibilities of the successful candidate will include constructing measurement setups, preparing samples, planning and conducting measurements, travelling to experimental facilities for measurement sessions, analysing data, interpreting results, drawing conclusions regarding the underlying physical mechanisms, presenting results at conferences, and preparing scientific publications, supervising interns and students.
