Jianwei Sun received his Ph.D in physics from Tulane University in 2010 and did his postdoc work there till 2013. In 2014, he moved to the College of Science and Technology at Temple University as a Research Assistant Professor of Physics. Jianwei Sun has been working on the development of density functional theory (DFT) and its applications for almost 10 years. He has designed several efficient and accurate nonempirical functionals that are drastically different from old seminal work and stimulating the rethinking and reconstruction of the old seminal work.  

Research Interests

  • Electronic Structure Theory, Quantum Chemistry, Condensed Matter Physics, Materials Science, and Surface Science. 
  • Density functional theory (DFT) and time-dependent DFT : Meta generalized gradient approximation and its hybrid, self-interaction correction, charge transfer, strong correlation, d- and f-electron systems, band gap, excitonic effects.
  • Fundamental properties of two-dimensional (2D) materials and 3D layered materials with and without defects: Optical, electrical, magnetic, thermal, mechanical, and dielectric properties. 
  • Surface catalysis: Surface adsorption and diffussion and water splitting
