Non-hermitian Density Matrices from Time-like Entanglement and Wormholes
Jonathan Harper, Taishi Kawamoto, Ryota Maeda +2
We extensively explore the connections between time-like entanglement and non-hermitian density matrices in quantum many-body systems. We classify setups where we encounter non-her…
Traversable AdS Wormhole via Non-local Double Trace or Janus Deformation
Taishi Kawamoto, Ryota Maeda, Nanami Nakamura +1
We study (i) Janus deformations and (ii) non-local double trace deformations of a pair of CFTs, as two different ways to construct CFT duals of traversable AdS wormholes. First, we…
A Strategy for Proving the Strong Eigenstate Thermalization Hypothesis : Chaotic Systems and Holography
Taishi Kawamoto
The strong eigenstate thermalization hypothesis (ETH) provides a sufficient condition for thermalization and equilibration. Although it is expected to be hold in a wide class of hi…
Holographic Local Operator Quenches in BCFTs
Taishi Kawamoto, Takato Mori, Yu-ki Suzuki +2
We present a gravity dual of local operator quench in a two-dimensional CFT with conformal boundaries. This is given by a massive excitation in a three-dimensional AdS space with t…
