[QE-users] Scalar Relativistic v.s. fully relativistic pseudopotential

[LEUNG Clarence]

Dear QE users,

When I choosing the psedopetential, it is noted that there are two pseudopotentials, Scalar Relativistic v.s. fully relativistic pseudopotential, what is the main difference？

For example, for Ni,

Pseudopotential type: USPP
Element: Ni
Functional: PBE
    Suggested minimum cutoff for wavefunctions:  75. Ry
    Suggested minimum cutoff for charge density: 476. Ry
    The Pseudo was generated with a Scalar-Relativistic Calculation
    Local Potential by smoothing AE potential with Bessel fncs, cutoff radius:   1.5000


the suggested cutiff is 75 Ry, it is so large for me.

Best regards,
