Abstract: Investigating the fundamental origins of Bekenstein-Hawking entropy remains a profound challenge within the realm of theoretical physics. This exploration is particularly pertinent to anti de Sitter (AdS) black holes, where it is posited that the entropy in question may be explained via the states of the holographic dual quantum field theory, in accordance with the AdS/CFT correspondence. In my talk, I will introduce the idea of gluing gravitational blocks for supersymmetric AdS black holes in String/M-theory, encompassing any spin and a wide array of electric and magnetic charges. This approach provides insights into the behavior of the partition function for the corresponding holographic dual field theory at large N.
