<div>Dear PWSCF developers,</div>
<div> I found that when I turn on an external electric field (tefield = .true.), I can not do spin-polarized calculation (LSDA = .false.). I am just curious whether there is any fundamental </div>
<div>difficulties to do spin-polarized calculation in the presence of an external electric field or it is just that this function is not implemented in QE.</div>
<div> Thank you very much.</div>
