Hi,<br> You can just try 'grep hamiltonian *f90' in $QE/PW directory.<br>it will give you hamiltonian information .<br>if you want to compute quantum conductance, then you can try to have a look at <br>$QE/PWCOND directory .

Dear users and developers,<br><br>I'm trying to modify PWSCF code and, first of all, I should get<br>Hamiltonian matrix. As far as I know, however, in PWSCF, the Hamiltonian<br>matrix elements are not stored in output files, even in the codes! ( am I
<br>right? )<br><br>Then, for example, how can I obtain green's function matrix<br>( G =[e - H]^(-1) ) without knowing Hamiltonian matrix in PWSCF?<br><br>My question is:<br><br>Can I obtain hamiltonian matrix in PWSCF? If not, do you have any
<br>recommendations for building hamiltonian matrix? Actually, I saw several<br>papers which calculate quantum conductance using quantum-espresso, and I<br>believe that authors built hamiltonian matrix from PWSCF!<br><br>
