Gifts from long-range interaction: Emergent gapless topological behaviors in quantum spin chain
Sheng Yang, Hai-Qing Lin, Xue-Jia Yu
Topology in condensed matter physics is typically associated with a bulk energy gap. However, recent research has shifted focus to topological phases without a bulk energy gap, exh…

Universal entanglement spectrum in gapless symmetry protected topological states
Xue-Jia Yu, Sheng Yang, Hai-Qing Lin +1
Quantum entanglement marks a definitive feature of topological states. However, the entanglement spectrum remains insufficiently explored for topological states without a bulk ener…
