Relativistically closed systems and the spacetime of an evaporating black hole
Abstract: I will report on work-in-progress on a program that attempts to describe relativistic systems in a consistent way by considering only "closed" systems to which we can ascribe unitary evolution. Such systems might extend to a full universe but can be much smaller (and have an associated horizon), and be finite or unending in duration. As an application and for its own sake, we apply this mode of thinking to an evaporating black hole, in an effort to produce both a maximally representative conformal spacetime diagram, and toward a self-consistent and intuitive description of the evaporation process including a more precise and general understanding of complementarity.
