Postdoctoral position at Ruhr University Bochum in simulation of quantum friction at solid-liquid interfaces, Germany
Postdoctoral Position in simulation of quantum friction at solid-liquid interfaces
A postdoctoral position is available in my group (https://tp3.physik.ruhr-uni-bochum.de/theoretical-physics-of-electrified-liquid-solid-interfaces/) in the physics department at the Ruhr University Bochum starting at latest in January 2027 to investigate the emerging phenomenon of quantum friction in low-dimensional materials. Recent work has shown that exciton-solvent interactions in single-walled carbon nanotubes can mediate non-equilibrium energy transfer at solid-liquid interfaces, revealing new mechanisms of nanoscale dissipation with potential applications in sensing, filtration, and blue-energy harvesting (1).
The project aims to develop a multiscale theoretical framework linking ultrafast excitonic processes to environmental dynamics, and to explore quantum friction beyond carbon nanotubes in a broader class of low-dimensional materials. Key challenges include first-principles modelling of excitons in realistic dielectric environments and understanding their coupling to liquids, soft matter, and interfaces.
Candidates should have a PhD in Physics, Chemistry, or Materials Science, with expertise in condensed matter theory, electronic structure methods, many-body physics, molecular simulations. Experience with computational methods and scientific programming is highly desirable. This position offers the opportunity to work within the cluster of excellence RESOLV (https://www.solvation.de/) at the forefront of quantum energy dissipation and interfacial phenomena in nanoscale systems in close collaboration with experimental groups.
For further information and to apply, please send an email to Prof. Marialore Sulpizi (marialore.sulpizi@rub.de) with a motivation letter and your CV, including the names and contact details of two possible referees.
