The Entanglement Wedge Polygon
Kosei Fujiki, Jonathan Harper, Tadashi Takayanagi +1
In this work we consider a particular codimension-1 region of a holographic spacetime which we call the entanglement wedge polygon (EWP). For a pure state and a partition of the bo…
Probing the bubble interior with entanglement entropy and bulk-cone singularities
Roberto Auzzi, Stefano Baiguera, Lihan Guo +2
In the thin wall approximation, we study a class of asymptotically AdS black holes which contain a spherically symmetric vacuum bubble with a different (positive or negative) cosmo…
Solitonic vortices and black holes with vortex hair in AdS
Roberto Auzzi, Stefano Bolognesi, Giuseppe Nardelli +2
We study soliton and black hole solutions with scalar hair in AdS in a theory with a Maxwell field and a charged scalar field with double trace boundary conditions, which can t…
Multipartite information in sparse SYK models
Norihiro Iizuka, Arkaprava Mukherjee, Sunil Kumar Sake +1
In quantum field theories that admit gravity dual, specific inequalities involving entanglement entropy between arbitrary disjoint spatial regions hold. An example is the negativit…
Holographic complexity of the extended Schwarzschild-de Sitter space
Sergio E. Aguilar-Gutierrez, Stefano Baiguera, Nicoló Zenoni
According to static patch holography, de Sitter space admits a unitary quantum description in terms of a dual theory living on the stretched horizon, that is a timelike surface clo…
