Dynamical Signatures of Floquet Topology in Wave Packet Dynamics
Xin Shen, Bing Lu, Yan-Qing Zhu
Periodically driven quantum systems, known as Floquet systems, provide a versatile platform for engineering novel topological phases absent in static settings. However, dynamically…
Identifying Oriented Spin Space Groups and Related Physical Properties Using an Online Platform FINDSPINGROUP
Yutong Yu, Xiaobing Chen, Yanzhou Zhu +5
Unconventional magnets that combine antiferromagnetic structures with ferromagnetic-like responses are essential for the development of next-generation spintronics. Their emergent…
Topological Insulators with Hybrid-order Boundary States
Yan-Qing Zhu, Zhen Zheng, Giandomenico Palumbo +1
We report the discovery of several classes of novel topological insulators (TIs) with hybrid-order boundary states generated from the first-order TIs with additional crystalline sy…
Synthetic spin-orbit coupling for the multispin models in optical lattices
Zhen Zheng, Yan-Qing Zhu, Shanchao Zhang +2
The essential role of synthetic spin-orbit coupling in discovering new topological matter phases with cold atoms is widely acknowledged. However, the engineering of spin-orbit coup…
Synthetic non-Abelian topological charges in ultracold atomic gases
Qi-Dong Wang, Yan-Qing Zhu, Shi-Liang Zhu +1
Topological phases associated with non-Abelian charges can exhibit a distinguished bulk-edge correspondence compared with Abelian phases, although elucidating this relationship rem…
Enumeration and representation theory of spin space groups
Xiaobing Chen, Jun Ren, Yanzhou Zhu +7
Those fundamental physical properties, such as phase transitions, Weyl fermions, and spin excitation, in all magnetic ordered materials, were ultimately believed to rely on the sym…
