Growing Einstein-Rosen Bridge with Multi-partite Entanglement

Takanori Anegawa, Akihiro Miyata, Shota Suzuki +1

Can quantum entanglement continue to grow even after the entanglement entropies of subsystems have saturated? We address this question using genuine multi-entropy, which probes mul…

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…

Entanglement Dynamics by (Non-)Unitary Local Operator Quenches in a 2D Holographic CFT

Weibo Mao, Akihiro Miyata, Masahiro Nozaki +1

In this paper, we investigate the time evolution of entanglement entropy and mutual information for the spatially-infinite systems where we act with a primary operator on the vacuu…

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…

Entanglement dynamics in 2d HCFTs on the curved background: the case of q-Möbius Hamiltonian

Chen Bai, Akihiro Miyata, Masahiro Nozaki

We will explore the dynamical property of non-equilibrium phenomena induced by two-dimensional holographic conformal field theory (2d holographic CFT) Hamiltonian on the curved spa…

Hawking-Page and entanglement phase transition in 2d CFT on curved backgrounds

Akihiro Miyata, Masahiro Nozaki, Kotaro Tamaoka +1

The thermodynamics and the entanglement properties of two-dimensional conformal field theories (d CFTs) on curved backgrounds are studied. By means of conformal mapping we study…
