A reorganized Hartree-Fock framework imposes tunable orbital locality by pairing local degrees of freedom with local solution conditions, maintaining efficient SCF optimization and competitive reaction-energy accuracy.
An analytic continuation method builds Bethe-Salpeter spectra in selected energy ranges from polarizability tensors sampled at a few complex frequencies via matrix-valued continued fractions.
Spatial statistics on voxelized structures using FFT correlations and PCA yield low-dimensional convex features that support accurate predictions with as few as 10 training samples.
A new workflow uses GW-derived ionization potentials and electron affinities, quasiparticle renormalization for polarization, the integer charge transfer model for pinning, and electrostatic potential shifts to predict adsorbate energy alignment on oxide/metal substrates.
Hydrogen tunneling makes H-abstraction reactions by C2H, OH, and CN competitive in TMC-1 despite low individual rates, affecting aromatic abundance predictions.
