A Novel Version of Gauge/Gravity Duality

This chapter is an overview of the works where a novel version of gauge/gravity duality was proposed to enhance the predictive power of a modified bag model developed for understanding the atomic nucleus in terms of quarks. The proposed version of duality predicts the main decay channel of the lightest glueball. Another implication of duality is that it explains why the periodic table contains a limited number of stable elements, and makes it possible to calculate the maximum allowable charge Z of absolutely stable heavy nuclei. Calculations show that Z ≈ 82, which is the charge of the Pb nucleus.
