Boundary Criticality at the Nishimori Multicritical Point
Sheng Yang, Xinyu Sun, Shao-Kai Jian
We study boundary criticality at the Nishimori multicritical point of the two-dimensional (2D) random-bond Ising model. Using tensor-network methods, we construct a family of micro…
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…
Exploring nontrivial topology at quantum criticality in a superconducting processor
Ziqi Tan, Ke Wang, Sheng Yang +37
The discovery of nontrivial topology in quantum critical states has introduced a new paradigm for classifying quantum phase transitions and challenges the conventional belief that…
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…
