Target substance/model

General systems. For QSGW, only up to around 10 atoms are supported because of load. Slab calculation is also possible, but is currently undergoing testing.

Physical quantities that can be computed

Quasiparticle energy, quasiparticle wave function, permittivity, spin fluctuation, etc.


LAPW, LMTO, GW, PMT, quasiparticle self-consistent GW。
