Ultra-soft pesudopotentials are build on top of a very hard<br>
norm-conserving pseupotential; this is not the original formulation by<br>
Vanderbilt, but as far as I know, widely used and accepted nowadays.<br>

In this specific case, the norm-conserving pseudo uses the<br>
Troullier-Martins formulation.<br>
