Floquet Majorana XYZ Codes with Tunable Logical Dynamics

Xinyu Sun, Hong Yao

We construct Floquet codes from the Majorana XYZ subsystem code with local realizations both in qubits and directly in microscopic Majorana modes with lattice size . For…

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 constraint…

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 $|\…

Holographic dual of defect CFT with corner contributions

Xinyu Sun, Shao-Kai Jian

We study defect CFT within the framework of holographic duality, emphasizing the impact of corner contributions. We model distinct conformal defects using interface branes that dif…
