Progress towards understanding ultranonlocality through the wavevector and frequency dependence of approximate exchange-correlation kernels
Niraj K. Nepal, Aaron D. Kaplan, J. M. Pitarke +1
In the framework of time-dependent density functional theory (TDDFT), the exact exchange-correlation (xc) kernel determines the ground-state energy, excited-state e…
Accurate and numerically efficient rSCAN meta-generalized gradient approximation
James W. Furness, Aaron D. Kaplan, Jinliang Ning +2
The recently proposed rSCAN functional [J. Chem. Phys. 150, 161101 (2019)] is a regularized form of the SCAN functional [Phys. Rev. Lett. 115, 036402 (2015)] that improves SCAN's n…
Classical turning surfaces in solids: When do they occur, and what do they mean?
Aaron D. Kaplan, Stewart J. Clark, Kieron Burke +1
Classical turning surfaces of Kohn-Sham potentials, separating classically-allowed regions (CARs) from classically-forbidden regions (CFRs), provide a useful and rigorous approach…
