The anti-de Sitter/conformal field theory (AdS/CFT) correspondence is a remarkable tool for analytically studying strongly coupled physics. Thanks to the AdS/CFT correspondence. strongly correlated quantum systems can be understood as weakly coupled gravity theories. which live in a holographic spacetime with an extra emergent dimension and constant negative curvature. https://www.roneverhart.com/Remedy-Essentials-Zinc-Skin-Protectant-Paste-4-oz-Tubes/
