| 14:00 - 15:00 Weekly Seminar HEPCo Group Geometry of Corners School PHYSICS Abstract: In this talk, I will first introduce the notion of corners, motivating why they are central in gauge theories. I will then discuss the geometric structure of a generic embedding of an isolated corner. This will allow us to derive the maximal embedded algebra for this corner, establishing thereof a general result, prior to a specific dynamics and gauge fixing. A family of bulk metrics adapted to the corner embedding will then be introduced, and used in Einstein gravity to derive Noether charges. The charge algebra, once the embedding map is dealt with carefully, turns out to be a centerless faithful representation of the v ... 17:00 - 18:00 IPM Holography virtual seminar On Maximum Complexity in Holography School PARTICLES AND ACCELERATORS Abstract: The notion of holographic computational complexity has been introduced to probe the interior of black holes, however it seems that the holographic version does not capture the all expected features of quantum computational complexity. In this talk we provide a modification to the former holographic proposals to make it up. Paper: arXiv:2103.05367v2 ( for participating in this event, please contact us: "particles@ipm.ir" ) |
