Advances and challenges of SCAN and r2SCAN density functionals in transition-metal compounds
Yubo Zhang, Akilan Ramasamy, Kanun Pokharel +4
Transition-metal compounds (TMCs) with open-shell d-electrons are characterized by a complex interplay of lattice, charge, orbital, and spin degrees of freedom, giving rise to a di…

How Semilocal Are Semilocal Density Functional Approximations? -Tackling Self-Interaction Error in One-Electron Systems
Akilan Ramasamy, Lin Hou, Jorge Vega Bazantes +4
Self-interaction error (SIE), arising from the imperfect cancellation of the spurious classical Coulomb interaction between an electron and itself, is a persistent challenge in mod…
