Exploring positron characteristics utilizing two new positron–electron correlation schemes based on multiple electronic structure calculation methods |
The self-consistent all-electron density (a) and positron density (c) (in unit of a.u., a.u. expresses atomic unit) on plane (110) for Al based on the FLAPW method and the fQMCGGA approximation. The ratios of all-electron density (b) or positron density (d) calculated by using the FLAPW method to that by using the ATSUP method. |
