CFT Dual for Timelike Geodesic in Lorentzian dS
Xing Huang, Chen-Te Ma
We construct the Euclidean CFT dual of a generic massive scalar in Lorentzian dS via analytic continuation. The resulting defect defines a -invariant state t…
Modular Average and Weyl Anomaly in Two-Dimensional Schwarzian Theory
Xing Huang, Chen-Te Ma
The gauge formulation of Einstein gravity in AdS background leads to a boundary theory that breaks modular symmetry and loses the covariant form. We examine the Weyl anomaly fo…
Emergence of Kinematic Space from Quantum Modular Geometric Tensor
Xing Huang, Chen-Te Ma
We generalize the Quantum Geometric Tensor by replacing a Hamiltonian with a modular Hamiltonian. The symmetric part of the Quantum Geometric Tensor provides a Fubini-Study metric,…
Growth of a renormalized operator as a probe of chaos
Xing Huang, Binchao Zhang
We propose that the size of an operator evolved under holographic renormalization group flow shall grow linearly with the scale and interpret this behavior as a manifestation of th…
U(1) CS Theory vs SL(2) CS Formulation: Boundary Theory and Wilson Line
Xing Huang, Chen-Te Ma, Hongfei Shu +1
We first derive the boundary theory from the U(1) Chern-Simons theory. The boundary action on an -sheet manifold appears from its back-reaction of the Wilson line. The reason is…
Berry Curvature and Riemann Curvature in Kinematic Space with Spherical Entangling Surface
Xing Huang, Chen-Te Ma
We discover the connection between the Berry curvature and the Riemann curvature tensor in any kinematic space of minimal surfaces anchored on spherical entangling surfaces. This n…
