Extracting central charge from ground-state overlaps of spatially deformed Hamiltonians
Chen Bai, Xinyu Sun, Liang-Hong Mo +1
We show that the conformal anomaly of a -dimensional conformal field theory can be extracted directly from a ground-state wave-function overlap associated with a spatial con…
Analytic Bootstrap for Boundary Conformal Field Theories with Interacting Boundaries
Xinyu Sun, Shao-Kai Jian, Hong Yao
We investigate boundary conformal field theories (BCFTs) with boundary interactions in and employing the analytic bootstrap. By deriving universal constrai…
Boundary Criticality at the Nishimori Multicritical Point
Sheng Yang, Xinyu Sun, Shao-Kai Jian
We study boundary criticality at the Nishimori multicritical point of the two-dimensional (2D) random-bond Ising model. Using tensor-network methods, we construct a family of micro…
Boundary operator expansion and extraordinary phase transition in the tricritical O(N) model
Xinyu Sun, Shao-Kai Jian
We study the boundary extraordinary transition of a three-dimensional (3D) tricritical model. We first compute the mean-field Green's function with a general coupling of $|\…
