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…
Aspects of holographic timelike entanglement entropy in black hole backgrounds
Mir Afrasiar, Jaydeep Kumar Basak, Keun-Young Kim
We study the holographic construction of timelike entanglement entropy (tEE) in black hole backgrounds in Lorentzian geometries. The holographic tEE is realized through extremal su…
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…
Holographic entanglement negativity for disjoint subsystems in
Jaydeep Kumar Basak, Himanshu Parihar, Boudhayan Paul +1
We propose a construction to compute the holographic entanglement negativity for bipartite mixed state configurations of two disjoint subsystems in higher dimensional conformal fie…
