AMIN = [real]
Default: AMIN = min(0.1,AMIX,AMIX_MAG)
Description: AMIN specifies the minimal mixing parameter in Kerker's initial approximation[1] to the charge-dielectric function used in the Broyden[2][3]/Pulay[4] mixing scheme (IMIX=4, INIMIX=1).
Kerker's initial approximation[1] for the charge-dielectric function is given by
where =AMIX, =BMIX, and =AMIN.
