PhD in Sub-THz spectroscopy of quantum materials

University of Cologne www.uni-koeln.de
The University of Cologne is one of the largest and most research-intensive universities in Germany, offering a wide range of subjects. With its six faculties and its interfaculty centres, it offers a broad spectrum of scientific disciplines and internationally outstanding profile areas, supported by the administration with its services.

The collaborative research center “Control and dynamics of quantum materials” (CRC 1238) brings together a team of scientists from exper- imental and theoretical physics. Our vision is to discover, understand, and control novel collective phenomena and new functionalities in quantum materials arising from the interplay of spin-orbit-coupling, correlations, and topology. More information can be found here: http://crc1238.uni-koeln.de/. The open PhD position (Prof. Hemberger group, CRC project B02) is concerned with solid-state spectroscopy in the frequency range from 1Hz to 500GHz at low temperatures and in high magnetic fields

YOUR TASKS
» Conduct and refine the broadband spectroscopic setup (frequen- cy response analyzers up to 10 MHz, network analyzers up to 20 GHz) and its magneto-cryogenic environment

» Advance the fiber based time-domain spectrometer (5 to 500 GHz)
» Investigate the electrodynamic properties and dynamical beha- vior of quantum materials and control the order-parameter dyna- mics via external fields

YOUR PROFILE
» Master‘s degree in physics or a related discipline » Basic knowledge of magnetic, thermodynamic, and transport
properties of condensed matter » Background in experimental solid state spectroscopy and in
low-temperature measurements » Good team working, English language skills, and presentation
skills are essential, as well as high-motivation to collaborate within an interdisciplinary research framework
WE OFFER YOU
» a competitive research project » a diverse and fair working environment » support in reconciling work and family life » flexible working time models » extensive advanced training opportunities » occupational health management offers » local transport ticket at a discount for UoC employees
