Chemical and optical control of chiral-domain dynamics in 1T-TaS
Qingzheng Qiu, Mengxian Zhao, Roman Mankowsky +14
Optical control of symmetry-breaking quantum phases is often constrained when one domain is strongly favored in equilibrium. This limitation is exemplified by the chiral charge-den…
Robust and tunable Floquet altermagnets in sliding A-type antiferromagnetic bilayers
Zhe Li, Lijuan Li, Mengxue Guan +1
Arranging the stacking orders of A-type antiferromagnetic (A-AFM) bilayers offers a practical pathway to realizing two-dimensional altermagnets. Previous proposals, however, rely o…
Floquet-engineered Valley Topology with Anisotropic Response in 1T'-WSe and Janus WSeTe monolayers
Zhe Li, Haijun Cao, Lijuan Li +3
Valley topology has emerged as a key concept for realizing new classes of quantum states. Here, we investigate Floquet-engineered topological phase transitions in anisotropic 1T'-W…
Light-engineered Multichannel Quantum Anomalous Hall Effect in High-order Topological Plumbene
Zhe Li, Fangyang Zhan, Haijun Cao +3
Floquet engineering severs as a forceful technique for uncovering high Chern numbers of quantum anomalous Hall (QAH) states with feasible tunability in high-order topologically ins…
Laser-engineered -point Topology in Trigonal Bismuthene
Zhe Li, Haijun Cao, Sheng Meng
The -point topology represents a significant segment in the family of topological insulators. Here we provide a comprehensive prediction of light-induced -point-based topol…
