Abstract
Modifications to the SCAN density functional form improve numerical stability for reliable pseudopotential generation while maintaining performance comparable to the original.
AI-generated summary
We propose modifications to the functional form of the SCAN density functional to eliminate numerical instabilities. This is necessary to allow reliable, automatic generation of pseudopotentials (including PAW potentials). The regularized SCAN is designed to match the original form very closely, and we show that its performance remains comparable.
