Current Research

Dr. Wai-Ning Mei’s research areas include: molecular dynamics studies of alkali halides and molecular solids, total energy electronic calculation of the ferroelectric polymers and highly correlated systems, electron structures of the nano-structures, surface structure determination, multiple-scattering analysis of the low-energy and photoemission spectra, neutron scattering from flux lattice in the type-II superconductors, lattice dynamics of long chain polymers, rotation and vibration spectra of the adsorbed molecules, and application of variational methods to the anharmonic, weakly bounded, tightly bounded, and double-well potentials. Specific computation techniques include lattice dynamics, molecular dynamics, multiple-scattering method, first-principle full-potential linear-augment-plane-wave (FLAPW) method, and self-consistent atomic deformation (SCAD) method together with the SMODES symmetry-analysis software packages.
