О размерности бра и кетов

Do bras and kets have dimensions? https://arxiv.org/abs/2008.03187
Claude Semay, Cintia Willemyns
The bra and ket notation introduced by Dirac and the dimensional analysis are two powerful tools for the physicist. Curiously, almost nothing is said about connections between these two topics in the literature. We show here that bras and kets have dimensions. This could help students to grasp a better comprehension of this abstract notation.
