Gaussian-based cutoff scheme on Hartree-Fock exchange term of dielectric-dependent potential

- Gaussian-based and Erfc short-range potentials for nonlocal exchange interaction.
- The schemes are applied to HF and hybrid density functional theory (DFT) methods.
- Gaussian-based short-range potential yields better similarity to the bare potential.
- Gaussian-based cutoff reproduces the dielectric constant and bandgap properties.
