Dear SIESTA Users, As it is well known, the macroscopic polarization has an ionic and an electronic component.
The electronic contribution to the macroscopic polarization is calculated using the geometric Berry phase approach. The ionic contribution, is defined as the sum of the atomic positions within the unit cell multiply by the ionic charges. Is there a way to get the the contribution of each term to the macroscopic polarization in the output file of SIESTA software?. Thanks a lot before, Karim
