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…
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…
