Multipartite entanglement of the topologically ordered state in a perturbed toric code
Yu-Ran Zhang, Yu Zeng, Tao Liu +3
We demonstrate that multipartite entanglement, witnessed by the quantum Fisher information (QFI), can characterize topological quantum phase transitions in the spin- t…
Observation of Square-Root Higher-Order Topological States in Photonic Waveguide Arrays
Juan Kang, Tao Liu, Mou Yan +7
Recently, high-order topological insulators (HOTIs), accompanied by topologically nontrivial boundary states with codimension larger than one, have been extensively explored becaus…
Unconventional quantum sound-matter interactions in spin-optomechanical-crystal hybrid systems
Xing-Liang Dong, Peng-Bo Li, Tao Liu +1
We predict a set of unusual quantum acoustic phenomena resulting from sound-matter interactions in a fully tunable solid-state platform, in which an array of solid-state spins in d…
Higher-Order Weyl-Exceptional-Ring Semimetals
Tao Liu, James Jun He, Zhongmin Yang +1
For first-order topological semimetals, non-Hermitian perturbations can drive the Weyl nodes into Weyl exceptional rings having multiple topological structures and no Hermitian cou…
