• Research Interests

  Mingquan He’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:

• Unconventional Superconductors-high temperature, topological, heavy fermion superconductors, etc.

• Quantum Spin liquids

• 2D Materials
