CFT derivation of entanglement phase transition in pseudo entropy
Hiroki Kanda, Tadashi Takayanagi, Zixia Wei
In this paper, we discuss the entanglement phase transition of pseudo entropy in CFTs. We focus on the case where the in-state and the out-state are different boundary states relat…
Brane Cosmology from AdS/BCFT
Kosei Fujiki, Hiroki Kanda, Michitaka Kohara +1
In this paper, we study the time-dependent dynamics of an end-of-the-world (EOW) brane in AdS with a scalar field localized on the brane. We mainly studied several aspects of holog…
The -theorem from Strong Subadditivity
Jonathan Harper, Hiroki Kanda, Tadashi Takayanagi +1
We show that strong subadditivity provides a simple derivation of the -theorem for the boundary renormalization group flow in two-dimensional conformal field theories. We work o…
Entanglement Phase Transition in Holographic Pseudo Entropy
Hiroki Kanda, Taishi Kawamoto, Yu-ki Suzuki +3
In this paper, we present holographic descriptions of entanglement phase transition using AdS/BCFT. First, we analytically calculate the holographic pseudo entropy in the AdS/BCFT…
