Topologically Enforced Lifshitz Multicriticality in One Dimension
Kuang-Hung Chou, Xue-Jia Yu
Recent advances have revealed that topology can further enrich the universality classes of quantum phase transitions, thereby extending beyond the traditional paradigms of statisti…
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…
Implementation and topological characterization of Weyl exceptional rings in quantum-mechanical systems
Hao-Long Zhang, Pei-Rong Han, Xue-Jia Yu +8
Non-Hermiticity can lead to the emergence of many intriguing phenomena that are absent in Hermitian systems, enabled by exceptional topological defects, among which Weyl exceptiona…
Measurement-Induced Entanglement Phase Transition in Free Fermion Systems
Han-Ze Li, Jian-Xin Zhong, Xue-Jia Yu
Measurement-induced entanglement phase transitions (MIET) highlight how local measurements drive quantum systems between area-law and volume-law entangled states. This review surve…
Experimental demonstration of spontaneous symmetry breaking with emergent multi-qubit entanglement
Ri-Hua Zheng, Wen Ning, Jia-Hao Lü +8
Spontaneous symmetry breaking (SSB) is crucial to the occurrence of phase transitions. Once a phase transition occurs, a quantum system presents degenerate eigenstates that lack th…
