========================== The core modules of the QP ========================== *** How are handled the DFT functionals in QP2 ? ================================================ The Exchange and Correlation energies/potentials can be accessed by the following providers energy_x energy_c potential_x_alpha_ao potential_c_alpha_ao potential_x_beta_ao potential_c_beta_ao These providers are automatically linked to the providers of the actual exchange/correlation energies of a given functional through the character keywords "exchange_functional" "correlation_functional" All the providers for the available functionals are in the folder "functionals", with one file "my_functional.irp.f" per functional. Ex : if "exchange_functional" == "sr_pbe", then energy_x will contain the exchange correlation functional defined in "functiona/sr_pbe.irp.f", which corresponds to the short-range PBE functional (at the value mu_erf for the range separation parameter) *** How to add a new functional in QP2 ====================================== Creating a new functional and propagating it through the whole QP2 programs is easy as all dependencies are handled by a script. To do so, let us assume that the name of your functional is "my_func". Then you just have to create the file "my_func.irp.f" in the folder "functional" which shoud contain +) if you're adding an exchange functional, then create the provider "energy_x_my_func" +) if you're adding a correlation functional, create the provider "energy_c_my_func" +) if you want to add the echange potentials, create the providers "potential_x_alpha_ao_my_func", "potential_x_beta_ao_my_func" which are the exchange potentials on the AO basis for the alpha/beta electrons +) if you want to add the correlation potentials, create the providers "potential_c_alpha_ao_my_func", "potential_c_beta_ao_my_func" which are the correlation potentials on the AO basis for the alpha/beta electrons That's all :) Then, when running whatever DFT calculation or accessing/using the providers: energy_x energy_c potential_x_alpha_ao potential_c_alpha_ao potential_x_beta_ao potential_c_beta_ao if exchange_functional = mu_func, then you will automatically have access to what you need, such as kohn sham orbital optimization and so on ...
