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…
A string-theoretical analog of non-maximal chaos in some Sachdev-Ye-Kitaev-like models
Jin Chen, Chen Ma, Chushun Tian
Very recently two of the present authors have studied the chaos exponent of some Sachdev-Ye-Kitaev (SYK)-like models for arbitrary interaction strength [1]. These models carry supe…
Study of Asymptotic Free Scalar Field Theories from Adaptive Perturbation Method
Chen-Te Ma, Hui Zhang
We focus on the behavior of (2+1)d and (5+1)d or theories in different regimes and compare the results obtained from the adaptive perturbation method with th…
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…
-Bracket for D-branes in Large R-R Field Background
Chen-Te Ma
The volume-preserving diffeomorphism is a key feature that characterizes the large constant R-R ()-form field background in a D-brane theory. It represents a symmetry of th…
A route from maximal chaoticity to integrability
Chen Ma, Chushun Tian
We study the chaos exponent of some variants of the Sachdev-Ye-Kitaev (SYK) model, namely, the $\Ns=1$ supersymmetry (SUSY)-SYK model and its sibling, the -SYK model which i…
