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 criticality in two-dimensional interacting topological insulators
Yang Ge, Hong Yao, Shao-Kai Jian
We study the boundary criticality in 2D interacting topological insulators. Using the determinant quantum Monte Carlo method, we present a nonperturbative study of the boundary qua…
Quantum Charge-4e Superconductivity and Deconfined Pseudocriticality in the Attractive SU(4) Hubbard Model
Zhou-Quan Wan, Huan Jiang, Xuan Zou +2
Unlike conventional charge-2e superconductors, a charge-4e superconductor exhibits long-range coherence of electron quartets rather than Cooper pairs. Clear zero-temperature realiz…
Boundary criticality in two-dimensional correlated topological superconductors
Yang Ge, Huan Jiang, Hong Yao +1
The presence of a boundary enriches the nature of quantum phase transitions. However, the boundary critical phenomena in topological superconductors remain underexplored so far. He…
Boundary criticality for the Gross-Neveu-Yukawa models
Huan Jiang, Yang Ge, Shao-Kai Jian
We study the boundary criticality for the Gross-Neveu-Yukawa (GNY) models. Employing interacting Dirac fermions on a honeycomb lattice with armchair boundaries, we use determinant…
