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…
Is Action Complexity better for de Sitter space in Jackiw-Teitelboim gravity?
Takanori Anegawa, Norihiro Iizuka, Sunil Kumar Sake +1
Volume complexity in dS remains up to a critical time, after which it suddenly diverges. On the other hand, for the dS solution in JT gravity there is a linear dilat…
Volume complexity of dS bubbles
Roberto Auzzi, Giuseppe Nardelli, Gabriel Pedde Ungureanu +1
In the framework of the static patch approach to de Sitter holography introduced in [arXiv:2109.14104], the growth of holographic complexity has a hyperfast behaviour, which leads…
A falling magnetic monopole as a holographic local quench
Nicolo Zenoni, Roberto Auzzi, Stefania Caggioli +2
An analytic static monopole solution is found in global AdS, in the limit of small backreaction. This solution is mapped in Poincaré patch to a falling monopole configuration,…
Geometry of quantum complexity
Roberto Auzzi, Stefano Baiguera, G. Bruno De Luca +3
Computational complexity is a new quantum information concept that may play an important role in holography and in understanding the physics of the black hole interior. We consider…
On subregion action complexity in AdS and in the BTZ black hole
Roberto Auzzi, Stefano Baiguera, Andrea Legramandi +3
We analytically compute subsystem action complexity for a segment in the BTZ black hole background up to the finite term, and we find that it is equal to the sum of a linearly dive…
On volume subregion complexity in Vaidya spacetime
Roberto Auzzi, Giuseppe Nardelli, Fidel I. Schaposnik Massolo +2
We study holographic subregion volume complexity for a line segment in the AdS Vaidya geometry. On the field theory side, this gravity background corresponds to a sudden quench…
Subsystem complexity in warped AdS
Roberto Auzzi, Stefano Baiguera, Arpita Mitra +2
We compute the ultraviolet divergences of holographic subregion complexity for the left and right factors of the thermofield double state in warped AdS black holes, both for th…
Complexity and action for warped AdS black holes
Roberto Auzzi, Stefano Baiguera, Matteo Grassi +2
The Complexity=Action conjecture is studied for black holes in Warped AdS space, realized as solutions of Einstein gravity plus matter. The time dependence of the action of the…
