Geometric realization of stress-tensor deformed field theory
Yun-Ze Li, Yunfei Xie, Song He
We present a semiclassical framework in which stress-tensor deformations of a quantum field theory (QFT) reorganize into a gravitational action evaluated at a metric saddle. The de…

Holographic Correlators of Boundary/Crosscap CFTs in Two Dimensions
Yun-Ze Li, Yunfei Xie, Song He
This work explores holographic correlators within the frameworks of two-dimensional Boundary Conformal Field Theory (BCFT) and Crosscap Conformal Field Theory (XCFT). Utilizing the…
