Where Multipartite Entanglement Localizes: The Junction Law for Genuine Multi-Entropy
Norihiro Iizuka, Akihiro Miyata
We uncover a "junction law" for genuine multipartite entanglement, suggesting that in gapped local systems multipartite entanglement is controlled and effectively localized near ju…
Energy Conditions and Quantum Information
Norihiro Iizuka, Akihiro Ishibashi, Kengo Maeda +2
The concept of energy lies at the foundation of physical science. In general relativity and quantum field theory, the positivity and conservation of energy are encapsulated by the…
A note on Centaur geometry -- probing IR de Sitter spacetime holography
Norihiro Iizuka, Sunil Kumar Sake
We explore a Centaur geometry in JT gravity, which is an asymptotically AdS spacetime but in the IR admits a dS bubble with another AdS geometry in the deep IR. Thus, this geometry…
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…
