Late Seminar Notice: Please Post Tuesday, September 5, 9:30 AM Harvard Math Language Picture Seminar Harvard University, Department of Physics Speaker: Maciej Dunajski, Professor of Mathematical Physics (Cambridge University) Abstract: I discuss the impact of the positive cosmological constant on the interplay between the equivalence principle in general relativity, and the rules of quantum mechanics. There is an ambiguity in the definition
of a phase of a wave function measured by inertial and accelerating observes which is a non-relativistic analogue of the Unruh effect. This will be put in the framework of a non—relativistic limit of twistor space. In-Person: 17 Oxford Street, Jefferson Building ,Rm 2453, Cambridge Zoom:
