Chiral Superconductivity in Periodically Driven Altermagnet/Superconductor Heterostructures
Xiaolin Wan, Zheng Qin, Fangyang Zhan +3
The interplay between magnetism and superconductivity provides a fertile ground for engineering exotic topological phases, while dynamical control via periodic driving offers a uni…
Light-induced Odd-parity Magnetism in Conventional Collinear Antiferromagnets
Shengpu Huang, Zheng Qin, Fangyang Zhan +3
Recent studies have drawn growing attention on non-relativistic odd-parity magnetism in the wake of altermagnets. Nevertheless, odd-parity spin splitting is often believed to appea…
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…
Gyrotropic Magnetic Effect in Black Phosphorus Irradiated with Bicircular Light
Fangyang Zhan, Xin Jin, Da-Shuai Ma +4
The gyrotropic magnetic effect (GME), which emerges as the low-frequency limit of natural gyrotopy, is a fundamental property of Bloch electrons on the Fermi surface in materials l…
Quantum Spin Hall Effect with Extended Topologically Protected Features in Altermangetic Multilayers
Zhiyu Chen, Fangyang Zhan, Zheng Qin +3
Conventional topological classification theory dictates that time-reversal symmetry confines the quantum spin Hall (QSH) effect to a classification, permitting only…
