Strong-to-Weak Spontaneous Symmetry Breaking from Wormholes in Holography
Taishi Kawamoto, Kenya Tasuki, Masahito Yamazaki
We study strong-to-weak spontaneous symmetry breaking (SWSSB) at finite temperature and its implications in holography. SWSSB is a novel critical phenomenon that arises only in mix…
Saddle Incompatibility Generates Genuine Multientropy in Heavy Local Quenches
Kosei Fujiki, Kenya Tasuki
We study the time evolution of tripartite genuine multientropy in heavy local quenches via AdS/CFT. Its linear response around the vacuum cancels pointwise for arbitrar…
Multi-entropy and the Dihedral Measures at Quantum Critical Points
Jonathan Harper, Ali Mollabashi, Tadashi Takayanagi +1
The multi-entropy and dihedral measures are a class of tractable measures for multi-partite entanglement, which are labeled by the Rényi index (or replica number) as in the Rén…
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…
Pseudo entropy under joining local quenches
Kotaro Shinmyo, Tadashi Takayanagi, Kenya Tasuki
We compute the pseudo entropy in two-dimensional holographic and free Dirac fermion CFTs for excited states under joining local quenches. Our analysis reveals two of its characteri…
