Data-Driven Optimization of Seminumerical Exchange for SIMD CPUs
Jesse DiCenso, Henryk Laqua, Martin Head-Gordon
We present a seminumerical exchange algorithm (SNK) based on the sn-LinK method [Laqua et al., J. Chem. Theory Comput. 16, 1456 (2020)], optimized for modern multi-core central pro…

Reduction of finite-size effects for second-order Møller-Plesset perturbation theory with singularity subtraction
Stephen Jon Quiton, Juan D. F. Pottecher, Martin Head-Gordon +1
Second-order Moller--Plesset perturbation theory (MP2) for periodic systems suffers from finite-size errors (FSEs) that have inverse volume scaling due to the Coulomb kernel singul…
