IBSE = 0 | 1
Default: IBSE = 0
Description: IBSE can be used to select the algorithm for solving the Bethe-Salpeter or Casida equation.
The following options are available to solve the Bethe-Salpeter or Casida equation:
- IBSE = 0: Exact diagonalization with old BSE driver
- IBSE = 1: Time evolution
- IBSE = 2: Exact diagonalization
- IBSE = 3: Lanczos algorithm
Mind: IBSE = 2 and IBSE = 3 only available for VASP version 6.5.0 and above.
