Topological Tricritical Ising Universality Class in One Dimension
Sheng Yang, Hai-Qing Lin, Xue-Jia Yu
Recent advances have revealed that quantum critical universality can be enriched by nontrivial topology. Here we study the tricritical point of the one-dimensional cluster O Brien-…
Topological Quantum Criticality in Quasiperiodic Ising Chain
Sheng Yang, Hai-Qing Lin, Xue-Jia Yu
Topological classifications of quantum critical systems have recently attracted growing interest, as they go beyond the traditional paradigms of condensed matter and statistical ph…
Topological physics in quantum critical systems
Xue-Jia Yu, Limei Xu, Hai-Qing Lin
Topology forms a cornerstone in modern condensed matter and statistical physics, offering a new framework to classify the phases and phase transitions beyond the traditional Landau…
Quantum entanglement of fermionic symmetry-enriched quantum critical points in one dimension
Wen-Hao Zhong, Hai-Qing Lin, Xue-Jia Yu
Quantum entanglement can be an effective diagnostic tool for probing topological phases protected by global symmetries. Recently, the notion of nontrivial topology in critical syst…
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…
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…
