Keyword descriptions

SECTION_PARAMETERS: string = DEFAULT

Usage: H

The name of the kind described in this section. [Edit on GitHub]

BASIS_SET: string

Keyword can be repeated.

Usage: BASIS_SET [type] [form] DZVP

References: VandeVondele2005, VandeVondele2007

Mentions:Preliminaries, ⭐Electronic band structure from GW, ⭐GW + Bethe-Salpeter equation

The primary Gaussian basis set (NONE implies no basis used, meaningful with GHOST). Defaults are set for TYPE {ORB} and FORM {GTO}. Possible values for TYPE are {ORB, AUX, MIN, RI_AUX, LRI, …}. Possible values for FORM are {GTO, STO}. Where STO results in a GTO expansion of a Slater type basis. If a value for FORM is given, also TYPE has to be set explicitly. [Edit on GitHub]

ECP_SEMI_LOCAL: logical = T

Lone keyword: T

Usage: ECP_SEMI_LOCAL {T,F}

Use ECPs in the original semi-local form. This requires the availability of the corresponding integral library. If set to False, a fully nonlocal one-center expansion of the ECP is constructed. [Edit on GitHub]

ELEC_CONF: integer

Usage: ELEC_COND n_elec(s) n_elec(p) n_elec(d) …

Specifies the electronic configuration used in construction the atomic initial guess (see the pseudo potential file for the default values). [Edit on GitHub]

Usage: FLOATING_BASIS_CENTER

This keyword makes all atoms of this kind floating functions, i.e. without pseudo or nuclear charge which are subject to a geometry optimization in the outer SCF. [Edit on GitHub]

GHOST: logical = F

Lone keyword: T

Usage: GHOST

Mentions:Preliminaries

This keyword makes all atoms of this kind ghost atoms, i.e. without pseudo or nuclear charge. Useful to just have the basis set at that position (e.g. BSSE calculations), or to have a non-interacting particle with BASIS_SET NONE [Edit on GitHub]

GPW_TYPE: logical = F

Lone keyword: T

Usage: GPW_TYPE

Force one type to be treated by the GPW scheme, whatever are its primitives, even if the GAPW method is used [Edit on GitHub]

HARD_EXP_RADIUS: real

Usage: HARD_EXP_RADIUS 0.9

KG_POTENTIAL: string = NONE

Aliases: KG_POT

Usage: KG_POTENTIAL

The name of the non-additive atomic kinetic energy potential. [Edit on GitHub]

KG_POTENTIAL_FILE_NAME: string = -

MAX_RAD_LOCAL: real = 2.45664397E+001

Usage: MAX_RAD_LOCAL 15.0

Max radius for the basis functions used to generate the local projectors in GAPW [Bohr] [Edit on GitHub]

MM_RADIUS: real = 0.00000000E+000 [angstrom]

Usage: MM_RADIUS {real}

Defines the radius of the electrostatic multipole of the atom in Fist. This radius applies to the charge, the dipole and the quadrupole. When zero, the atom is treated as a point multipole, otherwise it is treated as a Gaussian charge distribution with the given radius: p(x,y,z)Nexp(-(x2+y2+z2)/(2*MM_RADIUS2)), where N is a normalization constant. In the core-shell model, only the shell is treated as a Gaussian and the core is always a point charge. [Edit on GitHub]

Usage: NO_OPTIMIZE

Skip optimization of this type (used in specific basis set or potential optimization schemes) [Edit on GitHub]

PAO_BASIS_SIZE: integer = 0

Mentions:PAO-ML

The block size used for the polarized atomic orbital basis. Setting PAO_BASIS_SIZE to the size of the primary basis or to a value below one will disables the PAO method for the given atomic kind. By default PAO is disbabled. [Edit on GitHub]

SE_P_ORBITALS_ON_H: logical = F

Lone keyword: T

Usage: SE_P_ORBITALS_ON_H
