Research Interests

1) Low-dimensional or spin-resistant quantum magnetic materials. Nuclear magnetic resonance (NMR) is used to study the ordered-disordered and ordered-ordered quantum phase transitions of these materials, including novel magnetic ordered states, quantum spin liquid states, magnetic structures near quantum critical points, low-energy element excitation, fractional element excitation, etc.


2) Unconventional superconductivity. Nuclear magnetic resonance (NMR) is one of the important tools to study the magnetic structure, spin fluctuations, and pair-symmetry of superconducting materials. Through these studies, it is possible to reveal the possible competitive states, superconductivity mechanisms, and unconventional superconductivity in the materials.

3) Strongly correlated state control and extreme condition testing techniques, including the development of ionic liquid intercalation and doping effects, spectroscopy and transport testing at high pressure, strong magnetic field, and extremely low temperature.


Talent Cultivation

It is planned to recruit 1-2 master's or doctoral students every year, and undergraduate students are welcome to join the research group.
