The EDF related to the pseudopotential is obtained by averaging the
pseudopotential over the uncorrelated wavefunction (a Slater
determinant), that is,
For each term of the pseudopotential (1), we can write the
result of the averaging in the following way,
Once relations (33) are evaluated for each term of the pseudopotential, all terms of the NLO EDF are generated, with the EDF coupling constants becoming linear combinations of the pseudopotential strength parameters . Since the pseudopotentials are Galilean-invariant, the obtained EDF coupling constants obey the Galilean-invariance constraints [2]. Similarly, when parameters of the pseudopotential are restricted to obey the gauge-invariance conditions defined in Sec. 2.3, the resulting coupling constants correspond to a gauge-invariant EDF.
The 12 second-order isoscalar (isovector) coupling constants expressed by the 7 second-order pseudopotential parameters are given in Table 10 (Table 11). Similar expressions relating at fourth (sixth) order 45 (129) isoscalar and isovector coupling constants to 15 (26) pseudopotential parameters, are available in the supplemental material [24].
