Fast and scalable finite-element based approach for density functional theory calculations using projector-augmented wave method
Kartick Ramakrishnan, Sambit Das, Phani Motamarri
In this work, we present a computationally efficient methodology that utilizes a local real-space formulation of the projector augmented wave (PAW) method discretized with a finite…
