We review and extend recent progress on the quantum description of near-extremal black holes in the language of effective quantum field theory. With black holes in Einstein-Maxwell theory as the main example, we derive the low energy description of the AdS(2) region from a spacetime point of view. We also give a concise formula for the symmetry breaking scale, we … Read More

Abstract: I will discuss recent work on a Hayden & Preskill like setup for both maximally chaotic and sub- maximally chaotic quantum field theories. We act on the vacuum with an operator in a Rindler like wedge R and transfer a small subregion I of R to the other wedge. The chaotic scrambling dynamics of the QFT Rindler time evolution reveals … Read More
