ALF is a new function derived from the ideal free energy in MDFT that quantifies local angular order of solvent molecules, providing complementary information to polarization and charge density.
Archê implements accelerated SCF in OFMD to generate plasma EOS with linear scaling and GPU speedup, validated on aluminum against Abinit after adding a pseudopotential correction from an average-atom model.
The paper establishes an exact N-centered ensemble DFT formalism unifying neutral and charged excitations and introduces three practical strategies: weight-dependent scaling of ground-state functionals, quasi-degenerate ensemble perturbation theory, and quantum bath embedding for excited states.
i-DFT computes spectral and transmission properties of correlated quantum dots from Coulomb blockade to Kondo regimes, matching many-body results at reduced cost.
Ab initio calculations show that vacancy formation Gibbs energies in B2 MoTa drop much more steeply for Ta-site vacancies (2.1 eV) than Mo-site vacancies (1.1 eV) from 0 to 3000 K due to quasiharmonic and anharmonic vibrational effects.
Transition path sampling serves as an active learning engine to build machine-learned potentials accurate in barrier regions, enabling discovery of multiple protonation mechanisms in CO2 reduction on copper.

Temperature dependence of the Gibbs energies of formation of point defects in B2 MoTa from ab initio calculations
Ab initio calculations show that vacancy formation Gibbs energies in B2 MoTa drop much more steeply for Ta-site vacancies (2.1 eV) than Mo-site vacancies (1.1 eV) from 0 to 3000 K due to quasiharmonic and anharmonic vibrational effects.
