Monitoring a de Sitter universe through an anti-de Sitter window
Sarah Hoback, Daniel L. Jafferis, Zixia Wei
We propose that AdS gravity coupled to dS end-of-the-world branes is dual to a unitary holographic CFT with non-unitary conformal boundary conditions. These boundary co…
Pure states for subregions in gravity and their entanglement entropy
Zixia Wei
It is proposed that spatial subregions in quantum gravity can be assigned pure states, rather than mixed reduced density matrices. The state is prepared by a partially frozen gravi…
A Tale of Two Hartle-Hawking Wave Functions: Fully Gravitational vs Partially Frozen
Galit Anikeeva, Raphaël Dulac, Zixia Wei +1
We revisit the Hartle-Hawking wave function in AdS spacetime, where natural spatial slices are open and require an additional spacetime boundary. This leads to two constructions: a…
CFT derivation of entanglement phase transition in pseudo entropy
Hiroki Kanda, Tadashi Takayanagi, Zixia Wei
In this paper, we discuss the entanglement phase transition of pseudo entropy in CFTs. We focus on the case where the in-state and the out-state are different boundary states relat…
Wormholes with Ends of the World
Diandian Wang, Zhencheng Wang, Zixia Wei
We study classical wormhole solutions in 3D gravity with end-of-the-world (EOW) branes, conical defects, kinks, and punctures. These solutions compute statistical averages of an en…
Holographic Dual of Crosscap Conformal Field Theory
Zixia Wei
We propose a holographic dual for 2D CFT defined on closed non-orientable manifolds, such as the real projective plane and the Klein bottle . Such CFT…
