Hi, I used Gaussian code to apply a finite electric field to a molecule, now I'm trying to do the same with a periodic system with PWscf. I found in PWscf manual the 'lelfield' amd 'gdir' variables and I understood that I can define the direction of the field to be only the axis direction on reciprocal lattice. Is there any way to define the electric field direction with components of a*, b* and c*? In another words, a diagonal electric field through the cell?<br>
<br>Thank you very much.<br><br>Antônio<br>
