To Quantum Espresso community:<br> It seems that in version 4.2 phonon calculations can not be performed with LSDA+U. Is there any fundamental conflict between density functional perturbation theory and LSDA+U? Or is it just that this part is not implemented in PWscf yet? Is there any plan that this part will be implemented in near future?<br>
