PhD Confined Water - Quantum Electric Dipoles

The effect of collective dipolar interactions and some form of a long-range ordering in a confined water network, which was not exist in any other form of water, has been shown in a recent study. Such an engineered system can be systematically tuned to investigate the novel quantum states in electric dipolar systems; moreover, lays an opportunity to realize for the first time ferroelectricity in water.

We plan to utilize several experimental methods such as Fourier transform infrared spectroscopy and dielectric spectroscopy to explore the interaction of the dipoles in confined water systems, where low temperature and external pressure will used as tuning mechanisms. High pressure experiments will be performed with diamond anvil cells that will be incorporated to the already existing IR-spectrometers and impedance analyzer setups.

The project will be carried out in collaboration with in-house and international colleagues (experimental as well as theoretical). Therefore, we are looking for an eager Ph.D. candidate who would like to help to build up the pressure setups and take up the challenge of the optical and dielectric measurements. This ambitious Ph.D. student should have a good experimental skills and extraordinary scientific drive.
