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…
Entanglement Fractalization
Yao Zhou, Peng Ye
We numerically explore the interplay of fractal geometry and quantum entanglement by analyzing the von Neumann entropy (known as entanglement entropy) and the entanglement contour…
Detecting bulk and edge exceptional points in non-Hermitian systems through generalized Petermann factors
Yue-Yu Zou, Yao Zhou, Li-Mei Chen +1
Non-orthogonality in non-Hermitian quantum systems gives rise to tremendous exotic quantum phenomena, which can be fundamentally traced back to non-unitarity and is much more funda…
Quantum Entanglement of Non-Hermitian Quasicrystals
Li-Mei Chen, Yao Zhou, Shuai A. Chen +1
As a hallmark of pure quantum effect, quantum entanglement has provided unconventional routes to condensed matter systems. Here, from the perspective of quantum entanglement, we di…
