<div dir="ltr">I am working with QE and I want to do a phonon calculation in non-zero temperature in order to calculate the free energy of bcc-titanium. This phase is stable only in high temperatures. It is not possible to work with the zero temperature spectrum because it have negative (imaginary) frequencies In the pw_forum, Jiayi Yan wrote that this code exists but not published. Can I get this code somehow?<br>
Thank you very much<br>Uri Argaman<br>Ben-Gurion University<br>Israel<br></div>
