Multipartite information in sparse SYK models

Autor: Iizuka, Norihiro, Mukherjee, Arkaprava, Sake, Sunil Kumar, Zenoni, Nicolò

In quantum field theories that admit gravity dual, specific inequalities involving entanglement entropy between arbitrary disjoint spatial regions hold. An example is the negativity of tripartite information. Inspired by this, we investigate the anal

Holographic complexity of the extended Schwarzschild-de Sitter space

Autor: Aguilar-Gutierrez, Sergio E., Baiguera, Stefano, Zenoni, Nicoló

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 close to the cosmological horizon. In this manuscript, we compute several

Is Action Complexity better for de Sitter space in Jackiw-Teitelboim gravity?

Autor: Anegawa, Takanori, Iizuka, Norihiro, Sake, Sunil Kumar, Zenoni, Nicolò

Volume complexity in dS$_2$ remains $O(1)$ up to a critical time, after which it suddenly diverges. On the other hand, for the dS$_2$ solution in JT gravity there is a linear dilaton which smoothly grows towards the future infinity. From the dimensio

Volume complexity of dS bubbles

Autor: Auzzi, Roberto, Nardelli, Giuseppe, Ungureanu, Gabriel Pedde, Zenoni, Nicolo

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 to a divergence in a finite time. This is very different from the AdS
