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…

Structural Obstruction to Replica Symmetry Breaking for Multi-Entropy in Random Tensor Networks
Sriram Akella, Norihiro Iizuka
We study replica symmetry breaking (RSB) for multi-entropy in the random-tensor-network (RTN) domain-wall spin model. Our main result is that, within this framework, multi-entropy…

Tripartite entanglement in the HaPPY code is not holographic
Sriram Akella
Holographic states satisfy several entropic inequalities owing to the Ryu-Takayangi formula. A drawback of these inequalities is that they only use bipartite entanglement in their…
