[QE-users] Electron-phonon - tetra_example - alpha2f.x problem

2023-05-30 Thread سيدمحمد صندوقچي via users
Dear Experts, I tried to run the "tetra_example" in the PHonon directory of the qe-7.1 and 7.2. The outputs of alpha2f.x in this example ("aluminum.a2F.dat" and "al.a2F.out") are strange. Except for the frequency column, the other ones have zero values. ===

[QE-users] Regarding Charge density difference

2023-05-30 Thread Satyasiban Dash ph19d005
Dear users, I am planning to calculate charge density difference at interface of a heterostructure. So I underwent relaxation of cell ,then scf of hetero structure, so here are my small doubts 1. Do I need to delete one layer and calculate scf with same lattice cell and atomic position and do the

Dear Dr. Timrov, Thank you again! I'll read the paper you suggested.  I applied the equations I previously mentioned (M Jubair et al 2019 J. Phys. Commun. 3 055017) but the results were different I expected. I followed the steps in the hands-on to fill out the lanczos (changing the "itermax" fr

If you want to visualize the charge density variations induced by the formation of the interface, once you have the optimized structure of the heterostructure and its charge density rho_tot, you have to make, at frozen atomic positions two more scf calculations, obtained from the former by removing
