DESCRIPTION:Title: <a href="https://researchseminars.org/talk/qucos/1/">Ri
 ndler Bulk Reconstruction and Subregion Duality in AdS/CFT</a>\nby Sotaro 
 Sugishita (Nagoya University) as part of Quantum Cosmos Seminars\n\n\nAbst
 ract\nIn this talk\, we show that the AdS-Rindler reconstruction is incomp
 lete. CFT operators naively given by the holographic dictionary for the Ad
 S-Rindler reconstruction contain tachyonic modes\, which are inconsistent 
 with the causality and unitarity of the CFT. Therefore\, the subregion dua
 lity and the entanglement wedge reconstruction do not hold. We also find t
 hat the tachyonic modes in the AdS-Rindler patch lead to arbitrary high-en
 ergy or trans- Planckian modes in the global AdS. It means that the mode e
 xpansion of the Rindler patch is sensitive to the UV limit\, i.e.\, quantu
 m gravity. In addition\, the tachyonic modes are related to null geodesics
  connecting the past and future horizons. This talk is based on the paper 
 [arXiv:2207.06455] with Seiji Terashima.\n
