Generalized Free Fields in de Sitter from 1D CFT
Kanato Goto, Alexey Milekhin, Herman Verlinde +1
We show that a pair of identical large 1D CFTs, like the low-energy limit of the SYK model or a line-defect inside a higher dimensional CFT, contains a natural sub-algebra of o…
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…
Replica wormholes for an evaporating 2D black hole
Kanato Goto, Thomas Hartman, Amirhossein Tajdini
Quantum extremal islands reproduce the unitary Page curve of an evaporating black hole. This has been derived by including replica wormholes in the gravitational path integral, but…
Janus interface entropy and Calabi's diastasis in four-dimensional superconformal field theories
Kanato Goto, Lento Nagano, Tatsuma Nishioka +1
We study the entropy associated with the Janus interface in a 4 superconformal field theory. With the entropy defined as the interface contribution to an entangl…
Holographic Complexity Equals Which Action?
Kanato Goto, Hugo Marrochio, Robert C. Myers +2
We revisit the complexityaction proposal for charged black holes. We investigate the complexity for a dyonic black hole, and we find the surprising feature that the late-time gr…
Janus interface in two-dimensional supersymmetric gauge theories
Kanato Goto, Takuya Okuda
We study the Janus interface, a domain wall characterized by spatially varying couplings, in two-dimensional N=(2,2) supersymmetric gauge theories on the two-sphere. When the varia…
