Entanglement complexification transition driven by a single non-Hermitian impurity
Yao Zhou, Peng Ye
While non-Hermitian bulk systems and their sensitivity to boundary conditions have been extensively studied, how a non-Hermitian boundary affects the entanglement structure of Herm…
Quantum entanglement and non-Hermiticity in free-fermion systems
Li-Mei Chen, Yao Zhou, Shuai A. Chen +1
This topical review article reports rapid progress on the generalization and application of entanglement in non-Hermitian free-fermion quantum systems. We begin by examining the re…
Entanglement scaling behaviors of free fermions on hyperbolic lattices
Xiang-You Huang, Yao Zhou, Peng Ye
Recently, tight-binding models on hyperbolic lattices (discretized AdS space) have gained significant attention, leading to hyperbolic band theory and non-Abelian Bloch states. In…
Three-dimensional fracton topological orders with boundary Toeplitz braiding
Bo-Xi Li, Yao Zhou, Peng Ye
In this paper, we theoretically study a class of 3D non-liquid states that show exotic boundary phenomena in the thermodynamical limit. More concretely, we focus on a class of 3D f…
Measuring entanglement entropy and its topological signature for phononic systems
Zhi-Kang Lin, Yao Zhou, Bin Jiang +6
Entanglement entropy is a fundamental concept with rising importance in different fields ranging from quantum information science, black holes to materials science. In complex mate…
Hyperfine Structure of Quantum Entanglement
Liang-Hong Mo, Yao Zhou, Jia-Rui Sun +1
Quantum entanglement, crucial for understanding quantum many-body systems and quantum gravity, is commonly assessed through various measures such as von Neumann entropy, mutual inf…
