Holographic Entanglement and Causal Shadow in Time-Dependent Janus Black Hole
Yuki Nakaguchi, Noriaki Ogawa, Tomonori Ugajin
We holographically compute an inter-boundary entanglement entropy in a time-dependent two-sided black hole which was constructed in hep-th/0701108 by applying time-dependent Janus…
Holographic Heavy Quark Symmetry
Koji Hashimoto, Noriaki Ogawa, Yasuhiro Yamaguchi
We investigate the heavy quark spin symmetry, i.e. the mass degeneracy of pseudo-scalar and vector quarkonia at heavy quark limit, by using the gauge/gravity correspondence. We all…
Entanglement Entropy of de Sitter Space α-Vacua
Norihiro Iizuka, Toshifumi Noumi, Noriaki Ogawa
We generalize the analysis of arXiv:1210.7244 to de Sitter space α-vacua and compute the entanglement entropy of a free scalar for the half-sphere at late time.
On the Entanglement of Multiple CFTs via Rotating Black Hole Interior
Norihiro Iizuka, Noriaki Ogawa
We study the minimal surfaces between two of the multiple boundaries of 3d maximally extended rotating eternal black hole. Via AdS/CFT, this corresponds to investigating the behavi…
