System-environment dynamics of GHZ-like states in noninertial frames
Tinggui Zhang, Hong Yang, Shao-Ming Fei
Quantum coherence, quantum entanglement and quantum nonlocality are important resources in quantum information precessing. However, decoherence happens when a quantum system intera…
Duality, Criticality, Anomaly, and Topology in Quantum Spin-1 Chains
Hong Yang, Linhao Li, Kouichi Okunishi +1
In quantum spin-1 chains, there is a nonlocal unitary transformation known as the Kennedy-Tasaki transformation , which defines a duality between the Haldane phase a…
Symmetry-protected quantization of complex Berry phases in non-Hermitian many-body systems
Shoichi Tsubota, Hong Yang, Yutaka Akagi +1
We investigate the quantization of the complex-valued Berry phases in non-Hermitian quantum systems with certain generalized symmetries. In Hermitian quantum systems, the real-valu…
Symmetry-protected Topological Phases in Spinful Bosons with a Flat Band
Hong Yang, Hayate Nakano, Hosho Katsura
We theoretically demonstrate that interacting symmetry-protected topological (SPT) phases can be realized with ultracold spinful bosonic atoms loaded on the lattices which have a f…
Rigorous Results for the Ground States of the Spin-2 Bose-Hubbard Model
Hong Yang, Hosho Katsura
We present rigorous and universal results for the ground states of the spinor Bose-Hubbard model. The model includes three two-body on site interaction terms, two of which ar…
Uniform Quantification of Correlations for Bipartite Systems
Tinggui Zhang, Hong Yang, Xianqing Li-Jost +1
Based on the relative entropy, we give a unified characterization of quantum correlations for nonlocality, steerability, discord and entanglement for any bipartite quantum states.…
