Constructor & Destructor Documentation

mpqc::GFRealPole::GFRealPole ( const KeyVal & kv )

explicit

The KeyVal constructor.

Parameters

kv

the KeyVal object, it will be queried for all keywords of the WavefunctionProperty class, as well as the following keywords:

Keyword	Type	Default	Description
target	int	-1	target pole index, defined relative to the Fermi level; e.g., -1 denotes the first pole below the Fermi level, +1 denotes the first one above. In practice the Wavefunction class may use this as a initial guess rather than try to guarantee the index of the computed pole; refer to the documentation of the appropriate Wavefunction class

Note: This constructor overrides the default target precision to 1e-4 $\sim 3~{\rm meV}$ .

int mpqc::GFRealPole::target ( ) const

Returns: the target pole index (see the KeyVal ctor of GFRealPole for the explanation).
