i am calculating vibrational properties using QHA of espresso code<div>i have the fcc structure having 2 atoms in unit cell</div><div>i get the static energy -147.245069 Ry at zero pressure</div><div>after that i calculted vibrational properties at zero pressure which is given below</div>
<div><br></div><div>my question the out put f_vibrational energy is Ry/Cell</div><div>so i have to add the f_vibrational energy to the energy at T=0k</div><div>so whether i add the f_vibr or i have to divide anything in the vibrational energy which will be added to cold energy for my system having NaCl structure</div>
