Topological Tricritical Ising Universality Class in One Dimension
Sheng Yang, Hai-Qing Lin, Xue-Jia Yu
Quantum critical points can host symmetry-protected topological edge modes even when the bulk is gapless, giving rise to symmetry-enriched universality classes beyond the conventio…
Anomalous Dynamical Scaling at Topological Quantum Criticality
Menghua Deng, Sheng Yang, Chen Sun +2
We study the nonequilibrium driven dynamics at topologically nontrivial quantum critical points (QCPs), and find that topological edge modes at criticality give rise to anomalous d…
Generalized Li-Haldane Correspondence in Critical Dirac-Fermion Systems
Yuxuan Guo, Sheng Yang, Xue-Jia Yu
Topological phenomena in quantum critical systems have recently attracted growing attention, as they go beyond the traditional paradigms of condensed matter and statistical physics…
Deconfined criticality as intrinsically gapless topological state in one dimension
Sheng Yang, Fu Xu, Da-Chuan Lu +3
Deconfined criticality and gapless topological states have recently attracted growing attention, as both phenomena go beyond the traditional Landau paradigm. However, the deep conn…
Quantum Strong-to-Weak Spontaneous Symmetry Breaking in Decohered One Dimensional Critical States
Yuxuan Guo, Sheng Yang, Xue-Jia Yu
Symmetry breaking has been a central theme in classifying quantum phases and phase transitions. Recently, this concept has been extended to the mixed states of open systems, attrac…
Gapless Symmetry-Protected Topological States in Measurement-Only Circuits
Xue-Jia Yu, Sheng Yang, Shuo Liu +2
Measurement-only quantum circuits offer a versatile platform for realizing intriguing quantum phases of matter. However, gapless symmetry-protected topological (gSPT) states remain…
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…
Quantum phase transition and critical behavior between the gapless topological phases
Hao-Long Zhang, Han-Ze Li, Sheng Yang +1
The phase transition between gapped topological phases represents a class of unconventional criticality beyond the Landau paradigm. However, recent research has shifted attention t…
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…
