In AdS/CFT a charged Black hole is probably someway equivalent to introducing a chemical potential (Chemical potential) at the boundary theory. Is there a quick way to see how it is or how does this correspondence work?
I am sure it's well argued, but I haven't found a satisfactory explanation in any paper. Specially I will like to understand by connecting it with the thermodynamic case. In addition, it will be very helpful, if you can suggest me any introductory references or something with a nice explanation. Thanks!
