The CP2K Program Package Made Simple
CP2K is a versatile open-source software package for simulations across a wide range of atomistic systems, from isolated molecules in the gas phase to low-dimensional functional materials and interfaces, as well as highly symmetric crystalline solids, disordered amorphous glasses, and weakly interacting soft-matter systems in the liquid state and in solution. This review highlights CP2K's capabilities for computing both static and dynamical properties using quantum-mechanical and classical simu…

Semisimplicity of conformal blocks
We prove that braid group representations associated to braided fusion categories and mapping class group representations associated to modular fusion categories are always semisimple. The proof relies on the theory of extensions in non-Abelian Hodge theory and on Ocneanu rigidity. By combining this with previous results on the existence of variations in Hodge structures, we further show that such a braid group or mapping class group representation preserves a non-degenerate Hermitian form and …
