Diamagnetic Term

[Jagjit Kaur]

Dear Yambo Developers,

After the diagonalisation in BSE, in the eps output file, I get the diamagnetic terms printed:

Code: Select all

# Diamagnetic term                                
# Ao                                              :  -247.905334    [nel]
# A                                               :  -247.917587    [nel]

Can I know how these terms are calculated and what is the units. Is it Bohr^2? The equation used to calculate in the code might help.

Regards,
Jagjit
