The existence of subspace designs

open access: yesProceedings of the London Mathematical Society, Volume 131, Issue 1, July 2025.
Abstract We prove the existence of subspace designs with any given parameters, provided that the dimension of the underlying space is sufficiently large in terms of the other parameters of the design and satisfies the obvious necessary divisibility conditions. This settles an open problem from the 1970s.

Unveiling Hidden Intramolecular Non‐Covalent Interactions in a Neutral Serine, Its Zwitterion, Cluster, and Crystal by Features of Electron Density

open access: yesJournal of Computational Chemistry, Volume 46, Issue 17, June 30, 2025.
We reveal a new class of intramolecular noncovalent interactions called “latent” that lack bond paths yet stabilize molecules through subtle electronic effects. Using electron density and electronic pressure analysis, we classify them as “dynamic” or “static” and track their evolution across isolated molecules, molecular clusters, and crystals ...
