Cavity-induced multispin interactions and phase transitions in ultracold Fermi gases
Zhen Zheng, Shi-Liang Zhu, Z. D. Wang
The many-body physics of higher-spin systems is expected to host qualitatively new matter phases, but realizing them requires the controllable interactions between multispin compon…
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…
