RESEARCH
Using NMR technique, Prof. Zheng has so far conducted researches on superconductivity in high-Tc cuprates, iron pnictides, heavy fermion compounds, cobalt oxides and non-centrosymmetric materials. He has also developed unique techniques for the use at high pressures, low temperatures and high magnetic fields (including pulsed fields.)
In this project, he aims to study in particular the topological phenomena in non-centrosymmetric superconductors.
