<div dir="ltr"><div dir="ltr">Hi,</div><div dir="ltr"><br></div><div dir="ltr">I calculated phonon dispersion and compared it with other studies. However, dispersion is matched with every k direction except X-K. Would you please tell me how to solve the issue? Should I use a different pseudopotential? I am sharing here the details calculation if you can help.</div><div dir="ltr">Here is my result. At K, the graph is not smooth at all<br><div><br></div><div><img src="cid:ii_m2w7fs8m0" alt="image.png" width="542" height="366"><br></div><div><br></div><div>When I compared with other studies, I found the mismatch along the X-K direction.</div><div><br></div><div><img src="cid:ii_m2w7hnd51" alt="image.png" width="542" height="363"><br></div><div>Here is my <a href="http://scf.in">scf.in</a></div><div><img src="cid:ii_m2w7isgm2" alt="image.png" width="324" height="429"><br></div><div>Here is my <a href="http://ph.in">ph.in</a></div><div><img src="cid:ii_m2w7j87t3" alt="image.png" width="204" height="174"><br></div><div>Here is my <a href="http://q2r.in">q2r.in</a></div><div><img src="cid:ii_m2w7jncd4" alt="image.png" width="138" height="89"><br></div><div>And finally, this is matdyn.x</div><div><img src="cid:ii_m2w7keey5" alt="image.png" width="188" height="201"><br></div><div><br></div><div>Thank you so much.
