Note that this requires additional postprocessing calculations.<br><br>As for Gruneisen parameters, one could calculate the specific heat through QHA and the bulk modulus with PW, then use the relationship between them. (See the book of L. Anderson on equations of state, starting from page 6).<br><br>Hope this helps.<br><br>******************************<br>Bertrand SITAMTZE YOUMBI, Ph D<br>Laboratory of Material Sciences<br>University of Yaoundé I-Cameroon <br><br><br>--- En date de : <b>Mar 16.8.11, Payam Norouzzadeh <i><payam.norouzzadeh@gmail.com></i></b> a écrit :<br><blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left:

Does anybody know a good document about them?<br><br>Best regards,Payam Norouzzadeh<br></div>
