Product of Random States and Spatial (Half-)Wormholes
Kanato Goto, Yuya Kusuki, Kotaro Tamaoka +1
We study how coarse-graining procedure of an underlying UV-complete quantum gravity gives rise to a connected geometry. It has been shown, quantum entanglement plays a key role in…
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…
Wormholes and holographic decoherence
Takanori Anegawa, Norihiro Iizuka, Kotaro Tamaoka +1
We study a class of decoherence process which admits a 3 dimensional holographic bulk. Starting from a thermo-field double dual to a wormhole, we prepare another thermo-field doubl…
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…
Holographic Pseudo Entropy
Yoshifumi Nakata, Tadashi Takayanagi, Yusuke Taki +2
We introduce a quantity, called pseudo entropy, as a generalization of entanglement entropy via post-selection. In the AdS/CFT correspondence, this quantity is dual to areas of min…
A Field Theory Study of Entanglement Wedge Cross Section: Odd Entropy
Ali Mollabashi, Kotaro Tamaoka
We study odd entanglement entropy (odd entropy in short), a candidate of measure for mixed states holographically dual to the entanglement wedge cross section, in two-dimensional f…
