Going back to last week, when I presented my experiences with a “Specifications Grading” (SG) assessment format for my Chem2002 quantum chemistry course at #unb during the Kaleidoscope Teaching Showcase 2025, organised by the Centre for Enhanced Teaching and Learning. (1/4)

Fully Analytic Nuclear Gradients for the Bethe–Salpeter Equation The Bethe–Salpeter equation (BSE) formalism, combined with the GW approximation for ionization energies and electron affinities, is emerging as an efficient and accurate method for predicting optical excitations in molecules. In this Letter, we present the first derivation and implementation of fully analytic nuclear gradients for the BSE@G0W0 method. Building on recent developments for G0W0 nuclear gradients, we derive analytic nuclear gradients for several BSE@G0W0 variants. We validate our implementation against numerical gradients and compare excited-state geometries and adiabatic excitation energies obtained from different BSE@G0W0 variants with those from state-of-the-art wave function methods.

Pay attention, Canada. If Alberta is successful in this book banning, this will spread. Look around you, b/c this is how it starts. We're on the same ledge the US was on. And we either start fighting this right-wing rise now, or we follow the Americans over the edge.
