Dr. Ma Junzhang

Dr. Ma’s research mainly focuses on electronic structure of topological materials, superconductivity, low-dimensional materials, and correlated materials using Angle Resolved Photoemission Spectroscopy (ARPES).

Dr.Ma Junzhang joined the Department of Physics of City University of Hong Kong as an assistant professor in January 2021.



PhD, Institute of Physics, Chinese Academy of Science(2017)
BSc in Physics, Jilin University (2011)

Research interests

1) Electronic structure of topological materials including Dirac/Weyl semimetal, topological insulator, axion insulator, and topological superconductor
2) Unconventional superconductor
3) Coexistence of magnetic order with topological or superconducting states
4) Correlated systems: polaron and charge/spin density wave (CDW/SDW), trions, excitons, other new quantum phenomena induced by electron-boson coupling effect in low dimensional materials.
