On the Phases of Gravity

Eliezer Rabinovici (Racah Institute)


Abstract

Matter has many phases all the way from liquids and solids to topological ones. The standard model consists of three phases of gauge theories manifesting themselves as the electromagnetic interactions, the weak and the colored ones. In this lecture some of the possible phases of gravity will be described. This will be done by identifying the relevant degrees of freedom at different energy scales. In this context relations between the properties of the long time behavior of correlation functions in quantum field theory and the so called black hole information paradox will be examined. The consequences of scale invariance on the vacuum energy will be reviewed.
