报告摘要:  

 With the Compere-Song-Strominger(CSS) boundary conditions, AdS_3 is proposed to be dual to a warpedconformal field theory (WCFT). In a recent paper arXiv:1610.00727 the authorsgeneralize the Rindler method to calculate the holographic entanglement entropyfor warped conformal field theory (WCFT), and find thecorresponding geometric quantity is quite different compared to the RTsurface. In this talk, I would like to give a LM type of derivation for thisgeometric quantity. Similar to the LM prescription in the context of AdS_3/CFT_2, Iwill construct a new type of replicated geometry thus extend the replicastory of WCFT to the bulk. The new replicated geometry is quitedifferent from the one constructed by LM and may shed light on thegeneralization of LM prescription to general spacetime.
