[QE-users] Accuracy conduction bands

2020-07-22 Thread Lun Yue
band (e.g. the 50th conduction band), is of the same order of magnitude as |p_mn| for lower conduction bands. I was wondering whether this is physical? Or are the high-lying conduction bands calculated with bad numerical accuracy such that p_mn is not sensible to calculate? Best regards, Lun
