The quantum technology group at the Institute of Physics of the Unversity of Rostock is performing research on quantum sensors and their application. Much of the work in the group is focused on the nitrogen-vacancy (NV) center, a color defect in diamond which can serve as an atomically small magnetic field sensor. Notably, these atomically small sensors enable nuclear magnetic resonance spectroscopy on nanometer-small samples such as single molecules.
The group is presently seeking a new postdoc (m/f/d) to join our team. The person hired shall spearhead a line of research aiming to harness nanoscale NMR spectroscopy to investigate the surface layer of ice. Surprisingly, it is still not fully clear why ice is slippery, and a key to the puzzle could be exotic effects taking place at the surface of ice. For example, there is considerable evidence that the uppermost few nanometers of ice melt into a liquid even at temperatures where bulk water is fully frozen. In the present project we will apply nanoscale NMR spectroscopy as a novel tool to these questions. The work will comprise

• design and construction of diamond sensor chips that permit the study of ice freezing and melting in existing cryostats of the group.
• development and implementation of novel electron spin resonance and nuclear spin resonance pulse protocols to extract information on the structure and dynamics of the uppermost layer of ice.
• interpretation of the results and presentation of the insights on international conferences and in international publications.
