<div dir="ltr"><div><div>Hi All<br> After running QHA (implemented in Quantum espresso) I have got E_internal,F_vibration, Specific heat (C_v), Entropy etc. Does F_vibration correspond to Helmholtz free energy? If so, Can anybody please tell me that how can I calculate Gibbs free energy?<br>
</div> Thanks in advance.<br></div> Pratik<br></div>
