LFINITE_TEMPERATURE = [logical]
Default: LFINITE_TEMPERATURE = .FALSE.
Description: LFINITE_TEMPERATURE determines whether the finite- or or zero-temperature formalism of many-body perturbation theory is used for ACFDT/GW calculations.
This feature is available as of VASP.6.1.0 for ACFDT/RPA (ALGO=ACFDT[R|RK]) and low-scaling GW calculations (e.g. ALGO=G0W0R[K]). For LFINITE_TEMPERATURE=.TRUE., a compressed Matsubara frequency grid is used and allows for GW and RPA calculations for metallic systems.[1]
