Strong-to-Weak Spontaneous Symmetry Breaking from Wormholes in Holography
Taishi Kawamoto, Kenya Tasuki, Masahito Yamazaki
The paper studies a novel strong-to-weak spontaneous symmetry breaking that appears only in mixed states, demonstrating it via BTZ black holes and wormhole connections in the holog…
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…
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…
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…
Non-extremal Island in de Sitter Gravity
Peng-Xiang Hao, Taishi Kawamoto, Shan-Ming Ruan +1
This paper investigates the challenges and resolutions in computing the entanglement entropy for the quantum field theory coupled to de Sitter (dS) gravity along a timelike boundar…
Entanglement Entropy via Double Cone Regularization
Taishi Kawamoto, Yu-ki Suzuki
This paper proposes an alternative regularization method for handling the ultraviolet behavior of entanglement entropy. Utilizing an prescription in the Euclidean double cone…
