I have the following two questions:<br><br></div>(1) I have constructed hr_dat file after running BaTiO3_example. I have got all the matrix element real and matrix dimension is 9*9. <br>
</div> <br> Do the off-diagonal element of the matrix represent hoping ?<br></div> Do the diagonal element of the matrix represent orbital-energy?<br></div> Do the diagonal element of the matrix represent hopping and orbital energy both?<br>
</div> If yes , how can I get orbital energy ?<br><br></div><br>(2)Now the size of the Hamiltonian is 9*9. Can I decrease the size of Hamiltonian matrix ?<br><br></div>Please help me.<br><br></div>Regards<br></div>wasim<br>
