<div>Dear all and stefano:</div><div> Thanks for your reply. Do you mean there is no way to calculate the phonon dispersion of the same material at different pressures? As is known, the structures are </div><div>ususlly different at different pressures. But in priciple there is only one equilibrium structure when pressure is not apllied. Can the pressure factor be considered when we do phonon calculation? </div><div><div class="moz-cite-prefix"><br></div><blockquote cite="mid:tencent_2BD2545F335A8D770F04DD62@qq.com" type="cite"><br>
