<br>
is there anyway of fixing the Wannier centers so they don't move
during the minimization of the spread?<br>
<br>
This can be useful to identify symmetries or to assign some
physical meaning to certain Wannier functions (we<br>
are interested in "defining" an impurity, and sometimes the
Wannier functions move away from the impurity).<br>
<br>
Thanks,<br>
<br>
