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…
