Entangling independent particles by path identity
Kai Wang, Zhaohua Hou, Kaiyi Qian +4
Quantum entanglement -- correlations of particles that are stronger than any classical analogue -- is the basis for research on the foundations of quantum mechanics and for practic…
Realization of Hopf-link structure in phonon spectra: Symmetry guidance and High-throughput investigation
Houhao Wang, Licheng Zhang, Ruixi Pu +2
The realization of Hopf-link structure in the Brillouin zone is rather rare hindering the comprehensive exploration and understanding of such exotic nodal loop geometry. Here we fi…
Distinct topological excitonic insulators characterized by quantum geometry
Zhuowei Liu, Rui Wang, Baigeng Wang
Theintertwining of electron-hole correlation and nontrivial topology is known to give rise to exotic topological excitonic insulators. Here, we show that the involvement of quantum…
Magnetically tuned topological phase in graphene nanoribbon heterojunctions
Wei-Jian Li, Da-Fei Sun, Sheng Ju +2
The interplay between topology and magnetism often triggers the exotic quantum phases. Here, we report an accessible scheme to engineer the robust topology by intr…
Quantum-Classical Correspondence of Non-Hermitian Symmetry Breaking
Zhuo-Ting Cai, Hai-Dong Li, Wei Chen
Real-to-complex spectral transitions and the associated spontaneous symmetry breaking of eigenstates are central to non-Hermitian physics, yet a comprehensive and universal theory…
Quasiparticle interference in altermagnets
Hao-Ran Hu, Xiangang Wan, Wei Chen
A novel collinear magnetic phase, termed ``altermagnetism,'' has recently been uncovered, characterized by zero net magnetization and momentum-dependent collinear spin-splitting. T…
