Aspects of Pseudo Entropy in Field Theories
Ali Mollabashi, Noburo Shiba, Tadashi Takayanagi +2
In this article, we explore properties of pseudo entropy [1] in quantum field theories and spin systems from several approaches. Pseudo entropy is a generalization of entanglement…
Holographic moving mirrors
Ibrahim Akal, Yuya Kusuki, Noburo Shiba +2
Moving mirrors have been known as tractable setups modeling Hawking radiation from black holes. In this paper, motivated by recent developments regarding the black hole information…
Entanglement entropy in holographic moving mirror and Page curve
Ibrahim Akal, Yuya Kusuki, Noburo Shiba +2
We calculate the time evolution of entanglement entropy in two dimensional conformal field theory with a moving mirror. For a setup modeling Hawking radiation, we obtain a linear g…
Pseudo Entropy in Free Quantum Field Theories
Ali Mollabashi, Noburo Shiba, Tadashi Takayanagi +2
Pseudo entropy is an interesting quantity with a simple gravity dual, which generalizes entanglement entropy such that it depends on both an initial and a final state. Here we reve…
Direct Calculation of Mutual Information of Distant Regions
Noburo Shiba
We consider the (Renyi) mutual information, , of distant compact spatial regions A and B in the vacuum state of a free sc…
Entanglement Entropy and Decoupling in the Universe
Yuichiro Nakai, Noburo Shiba, Masaki Yamada
In the expanding universe, two interacting fields are no longer in thermal contact when the interaction rate becomes smaller than the Hubble expansion rate. After decoupling, two s…
