Title: polarization quantum
Post by: jinylee on April 3, 2014, 16:21

Dear ATK team,

After I calculated 'polarization', I got several polarization values.
Among them, I understood pi(ionic), pe(electronic), Pt(pi+pe), and total fractional and cartesian polarizations.
But I cannot understood 'polarization quantum'. It has same unit C/m^2 as the total cartesian polarization, but the value(order of magnitude) are totally different.
I wonder what is the difference between total cartesian polarization and polarization quantum, and what is the real polarization value which can be comparable with experimental data.

Thank you for your answer in advance.

See http://quantumwise.com/documents/tutorials/latest/Polarization/index.html/chap.introduction.html#sect1.introduction.theory for a more detailed description of the various quantities.
