Detailed Description

Populates a matrix with the matrix elements of a QED vacuum polarization potential.

Constructor & Destructor Documentation

qedvp()

subroutine grasp_rciqed_qed_vp::qedvp::qedvp

(

real(real64), dimension(:, :), intent(out)

matrix

)

Populates matrix with the full QED vacuum polarization matrix elements in the orbital basis.

The matrix element values are integrated using the vp_vac{2,4} global arrays from this module, which contains both the Uehling and Källen-Sabry terms.

Parameters

matrix

An NW x NW real64 array for storing the matrix elements.

Member Function/Subroutine Documentation

qedvp_type()

subroutine grasp_rciqed_qed_vp::qedvp::qedvp_type	(	integer, intent(in)	vptype,
		real(real64), dimension(:, :), intent(out)	matrix
	)

Populates matrix with the matrix elements of the VP potential corresponding to a contribution defined by vptype.

The values of vptype correspond to the following VP contributions:

1. Uehling
2. Källén-Sabry

Parameters

vptype	Integer specifying the VP contribution.
matrix	An NW x NW real64 array for storing the matrix elements.
