Holographic measurement in CFT thermofield doubles
Stefano Antonini, Brianna Grado-White, Shao-Kai Jian +1
We extend the results of arXiv:2209.12903 by studying local projective measurements performed on subregions of two copies of a CFT in the thermofield double state and investi…
Universal chaotic dynamics from Krylov space
Johanna Erdmenger, Shao-Kai Jian, Zhuo-Yu Xian
Krylov complexity measures the spread of the wavefunction in the Krylov basis, which is constructed using the Hamiltonian and an initial state. We investigate the evolution of the…
Holographic measurement and quantum teleportation in the SYK thermofield double
Stefano Antonini, Brianna Grado-White, Shao-Kai Jian +1
According to holography, entanglement is the building block of spacetime; therefore, drastic changes of entanglement will lead to interesting transitions in the dual spacetime. In…
Holographic measurement and bulk teleportation
Stefano Antonini, Gregory Bentsen, ChunJun Cao +3
Holography has taught us that spacetime is emergent and its properties depend on the entanglement structure of the dual theory. In this paper, we describe how changes in the entang…
Complexity growth of operators in the SYK model and in JT gravity
Shao-Kai Jian, Brian Swingle, Zhuo-Yu Xian
The concepts of operator size and computational complexity play important roles in the study of quantum chaos and holographic duality because they help characterize the structure o…
Violation of the viscosity/entropy bound in translationally invariant non-Fermi liquids
Xian-Hui Ge, Shao-Kai Jian, Yi-Li Wang +2
The shear viscosity is an important characterization of how a many-body system behaves like a fluid. We study the shear viscosity in a strongly interacting solvable model, consisti…
Quantum criticality and duality in the SYK/AdS chain
Shao-Kai Jian, Zhuo-Yu Xian, Hong Yao
We show that the quantum critical point (QCP) between a diffusive metal and ferromagnetic (or antiferromagnetic) phases in the SYK chain has a gravitational description correspondi…
