Signatures of global symmetry violation in relative entropies and replica wormholes
Yiming Chen, Henry W. Lin
It is widely believed that exact global symmetries do not exist in theories that admit quantum black holes. Here we propose a way to quantify the degree of global symmetry violatio…

Bra-ket wormholes in gravitationally prepared states
Yiming Chen, Victor Gorbenko, Juan Maldacena
We consider two dimensional CFT states that are produced by a gravitational path integral. As a first case, we consider a state produced by Euclidean evolution followed by…

Replica wormhole and information retrieval in the SYK model coupled to Majorana chains
Yiming Chen, Xiao-Liang Qi, Pengfei Zhang
Motivated by recent studies of the information paradox in (1+1)-D anti-de Sitter spacetime with a bath described by a (1+1)-D conformal field theory, we study the dynamics of secon…
