Genuine Multi-Entropy in Abelian Chern--Simons Theory: Exact Key-Ring Collapse and Its Breakdown for Generic Link States
Yen-Cheng Chang, Kaberi Goswami, Norihiro Iizuka +1
We study genuine multi-entropy in Abelian Chern-Simons theory. For key-ring link states, where only the linking numbers between one distinguished component and the rem…
Genuine Multi-Entropy in the Toric Code
Sriram Akella, Norihiro Iizuka, Akihiro Miyata
We study genuine multi-entropy as a diagnostic of multipartite entanglement in the toric code, which provides a controlled setting for probing multipartite structures in topologica…
Emergent Closed Universes in Symmetric Orbifold CFTs
Akihiro Miyata, Keigo Horikoshi, Hiromasa Tajima +1
We identify closed universe sectors in large symmetric orbifold CFTs with holographic duals. Starting from tensor product states built out of a finite dimensional low energy su…
The Junction Law for Multipartite Entanglement in Confining Holographic Backgrounds
Norihiro Iizuka, Akihiro Miyata
We investigate how the junction law for multipartite entanglement is realized in confining holographic backgrounds, using genuine multi-entropy (GM) as our main diagnostic. We firs…
Multipartite Markov Gaps and Entanglement Wedge Multiway Cuts
Norihiro Iizuka, Akihiro Miyata, Mitsuhiro Nishida
The Markov gap, defined as the difference between reflected entropy and mutual information, serves as a diagnostic for quantum recoverability and multipartite entanglement. In holo…
