polarization quantum to obtain a meaningful polarization. n is an
integer.
Consider a simple dielectric like MgO at zero field. pw.x may give you
different dipoles in all directions, although physically in all
Hi folks
I am trying to perform some finite field calculations on a
moderate-sized cell (~1000 Ang^3), using PW example 10 as a guide.
When doing a zero field calculation (all efield_cart zero) the total
energy converges happily to whatever level I want (e.g. conv_thr=1.d-9).
However, the
