WebNov 23, 2024 · Recently I am trying to calculate the BSE and IQP transition dipole based on VASP lecture on BSE and BSE fatband. However, I have a few questions regarding the BSE and IQP oscillator strength. From the slides, it says that the BSE oscillator strength is: $$ \tag{1} ( f_{ck} - f_{vk} ) F_{cvk} A_{cvk} ^2 $$ where the IQP oscillator strength is: WebForceConstant. ¶. class py4vasp.data.ForceConstant(data_context, **kwargs) ¶. Bases: Refinery, Mixin. The force constants (second derivatives of atomic displacement). You can use this class to extract the force constants of a linear response calculation.
