报告题目:  Holography of Information and Massive Islands

报告人: Suvrat Raju (ICTS, Bangalore)

报告时间:  2021年10月27日下午3点

报告地点: 吉林大学中心校区物理楼302(ZOOM ID: 837 0640 4041)


报告摘要:

We will review recent results that suggest that, in any standard theory of quantum gravity, information available on the bulk of a Cauchy slice must also be available near the boundary of the slice. These ideas indicate how holography should be extended to four dimensional asymptotically flat spacetimes but they also shed light on the origins of AdS/CFT. We contrast this picture with the paradigm of islands and argue that islands are consistent only in theories of massive gravity.
