<p>Hi everyone,</p>
<p><br>
</p>
<p>I am told that band.x program can output momentum matrix elements. However, I cannot make sense of the output file p_avg.dat. For example, I think momentum matrix elements should be generally complex, but I see no such indications in the output file. So,
what's the format of p_avg.dat?</p>
