    Phonon Density of States (PDOS) at Gamma Point

    Hello everyone! I'm trying to replicate phonon density of states (PHDOS) diagrams for some solids using Quantum Espresso. The usual way I do it is the following one: scf calculation at minima (pw.x) Calculation of dynamical matrix in reciprocal space with nq=1 or 2 (ph.x) Calculation of...

    A Quantum Espresso Tutorial: h-Boron Phosphide Variable-Cell Relaxation

    Hello my dear fellows, how're you doing? I'm trying to learn how to use Quantum Espresso, and in order to do this, I'm trying to simulate a hexagonal boron phosphide primary cell. At the end of the simulation, the structure seems to be fine, but sometimes the distance of the atoms are too short...

    Problem in convergence in Quantum espresso

    I have constructed mono layer slab of rutile TiO2 (110) with 11 Angstroms vacuum between two layers. I used the Quantum wise software for the construction of the slab. Then I have exported the Quantum espresso input from Quantum wise software. Now the problem is the SCF calculations are not...

    Which code has superior pseudopotentials for ab initio quantum calculations?

    Guys, I have a questiom. Which do you think is better to use when it comes to ab initio quantum calculations the VASP code or the ESPRESSO code. I am a beginner in computational physics and I would like to know the difference. If you can help me in that, I would more than grateful. Thanks
