Finite- Operator Algebras and the Hilbert Space of Bilocal Holography
Byoungjoon Ahn, Robert de Mello Koch, Vatsal Garg +2
We give an operator-algebraic and representation-theoretic description of the Hilbert spaces of finite- bilocal holography. This work is a sequel to the finite- Hilbert space…
Finite Hilbert Spaces of Bilocal Holography
Robert de Mello Koch, Antal Jevicki, Junggi Yoon
For vector/AdS and dS holography we establish the structure of the emergent Hilbert space. This is done through implementation of finite trace relations on the infinite collect…
L-entropy: A new genuine multipartite entanglement measure
Jaydeep Kumar Basak, Vinay Malvimat, Junggi Yoon
We advance ``Latent entropy" (L-entropy) as a novel measure to characterize genuine multipartite entanglement in pure states, applicable to quantum systems with both finite and inf…
Multipartite Non-local Magic and SYK Model
Vinay Malvimat, Matthieu Sarkis, Yena Suk +1
We investigate the structure of quantum magic in interacting disordered fermionic systems, quantifying non-stabilizerness via the fermionic stabilizer Rényi entropy (SRE). To resol…
Probing the Hierarchy of Genuine Multipartite Entanglement with Generalized Latent Entropy
Byoungjoon Ahn, Jaydeep Kumar Basak, Keun-Young Kim +3
We introduce generalization of the recently proposed \textit{Latent Entropy} (L-entropy) \cite{Basak:2024uwc} as a refined measure of genuine multipartite entanglement (GME) in pur…
A New Genuine Multipartite Entanglement Measure: from Qubits to Multiboundary Wormholes
Jaydeep Kumar Basak, Vinay Malvimat, Junggi Yoon
We introduce the \textit{Latent Entropy} (L-entropy) as a novel measure to characterize the genuine multipartite entanglement in quantum systems. Our measure leverages the upper bo…
