Public Member Functions | |
| DiagramRPA (const DiracOperator::TensorOperator *const h, const std::vector< DiracSpinor > &basis, const HF::HartreeFock *in_hf, const std::string &atom="Atom") | |
| Normal constructor: needs core to split basis: only uses basis. | |
| DiagramRPA (const DiracOperator::TensorOperator *const h, const DiagramRPA *const drpa) | |
| Second constructor: copies over W matrices (depend only on k/pi) | |
| virtual void | solve_core (const double omega, int max_its=200, const bool print=true) override final |
| Itterates the RPA equations for core electrons. | |
| virtual Method | method () const override final |
| Returns RPA method. | |
| virtual double | dV (const DiracSpinor &Fa, const DiracSpinor &Fb) const override final |
| Calculates RPA correction to matrix element: <A||dV||B> | |
| double | dV_diagram (const DiracSpinor &Fa, const DiracSpinor &Fb) const |
| virtual void | clear () override final |
| Clears the t_am and t_ma RPA ME's [RPA ME's for hole-excited] @Details If a previous run failed, can clear t_am's + re-try. | |
| void | update_t0s (const DiracOperator::TensorOperator *const h=nullptr) |
| Updates lowest-order t_am matrix elements and resets RPA (+updates operator) | |
| void | grab_tam (const DiagramRPA *const drpa) |
| Copies the tam (and tma) values across from different RPAD. If two operators are similar, this can save time on the itterations. | |

| DiagramRPA (const DiagramRPA &)=default | |
