Research Interests
Yisheng Chai's group is focusing on the quantum phenomenon of strong correlated materials under extreme conditions(low temperature and strong magnetic fields) by means of electrical and thermal transport, thermal-expansion, magnetostriction, specific heat, magnetization and point-contact spectroscopy. Current ongoing research covers the following topics:
Coupling behavior of single phase and composite multiferroic and magnetoelectric
Superconductivity and strong correlation system
Development of thermal transport measurement, high magnetic field measurement and other magnetic measurement methods
