The eigenvectors are, of course, the Bloch wavefunctions.<br> <br> Because the hamiltonian is periodic it commutes with the translation<br> operator, you can diagonalize both the hamiltonian and the translation<br> operator at the same time. As a consequence each Bloch wavefunction has a<br> well-defined energy (hamiltonian's eigenvalue) and k-point (translation<br> eigenvalue). Using both eigenvalues you can classify the states without<br> ambiguity, except where the bands cross.<br> <br> > And also how do we choose k points while performing a band structure<br> > calculation in quantum espresso when we are having 330 atoms.<br> <br> It does not depend on the number of atoms.<br> <br> You have to test the convergence at fixed smearing. E.g. you choose a<br> smearing that's small enough for you, than you increase the number of<br> k-points until total energy converges. You may then try again for a<br> smaller/larger smearing and see if the results are consistent.<br> <br> I would advise starting with a smaller system, it would take ages to do it<br> on 330 atoms. Keep in mind that the number of k-points needed for an<br> accurate sampling is directly proportional to the size of the Brillouin<br> zone, hence inversely proportional to the size of the cell.<br> <br> E.g. if you estimate that 6x6x6 k-points converge a certain calculation<br> than 3x3x3 k-points will be converge a 2x2x2 supercell to exactly the same<br> level.<br> <br> Best regards<br> <br> <br> --<br> Lorenzo Paulatto<br> SISSA & DEMOCRITOS (Trieste)<br> phone: +39 040 3787 511<br> skype: paulatz<br> www: <a href="http://people.sissa.it/~paulatto/">http://people.sissa.it/~paulatto/</a><br> <br> *** save italian brains ***<br> <a href="http://saveitalianbrains.wordpress.com/">http://saveitalianbrains.wordpress.com/</a><br> <br> <br> ------------------------------<br> <br> Message: 6<br> Date: Fri, 11 Sep 2009 13:59:05 +0200<br> From: Stefano de Gironcoli <<a href="mailto:degironc@sissa.it">degironc@sissa.it</a>><br> Subject: Re: [Pw_forum] K Points and Band structures<br> To: PWSCF Forum <<a href="mailto:pw_forum@pwscf.org">pw_forum@pwscf.org</a>><br> Message-ID: <<a href="mailto:4AAA3B89.9020002@sissa.it">4AAA3B89.9020002@sissa.it</a>><br> Content-Type: text/plain; charset=ISO-8859-1; format=flowed<br> <br> Shaptrishi Sharma wrote:<br> > Hi QEs users,<br> ><br> > Can anybody please help me in understanding what are the k points ??
