Topological resolution of conical intersection seams and the coupled cluster bifurcation via mixed Hodge modules

Prasoon Saurabh ยท 2025

The rigorous description of Conical Intersections (CIs) remains the central challenge of non-adiabatic quantum chemistry. While the ``Yarkony Seam'' -- the $(3N-8)$-dimensional manifold of degeneracy โ€ฆ

Generation of Helical states -- breaking of symmetries, Curie's principle, and excited states

Julia Sabalot-Cuzzubbo, Didier Begue, Jacky Cresson ยท 2021

Following previous work of M.H. Garner, R. Hoffmann, S. Rettrup and G.C. Solomon, we discuss the generation of helical molecular orbitals (MOs) for linear chains of atoms. We first give a definition oโ€ฆ
