Symmetry-enforced third-order nonlinear thermal Hall effects in altermagnets
Yun-Mei Li, Jiacheng Yao, Hua Wang +1
Thermal Hall effect (THE) is a powerful probe of material properties, even in insulators. Here we investigate the thermal response of altermagnets by developing a theory on Berry c…
Quantized Quadrupole Superconductors
Yun-Mei Li, Yongwei Huang, Kai Chang
We introduce a class of superconductors termed "quantized quadrupole superconductors" that support Majorana corner modes according to the bulk-corner correspondence, distinct from…
Finite-temperature topological magnons in honeycomb ferromagnets with sublattice asymmetries
Lin-Gang Wei, Yun-Mei Li
The Comment [Y.-M. Li, B. Wei, and K. Chang, Phys. Rev. Lett. 132, 219601 (2024)] pointed out that it is incorrect to predict the temperature-driven topological phase transition of…
Stark Effects of Rydberg Excitons in a Monolayer WSe2 P-N Junction
Zhen Lian, Yun-Mei Li, Li Yan +6
The enhanced Coulomb interaction in two-dimensional (2D) semiconductors leads to the tightly bound electron-hole pairs known as excitons. The large binding energy of excitons enabl…
Anti-helical edge magnons in patterned antiferromagnetic thin film
Yun-Mei Li
Helical edge states in topological insulators give counterpropagating spin current on the two parallel edges. We here propose anti-helical edge states of magnons in patterned antif…
Temperature-Induced Magnonic Chern Insulator in Collinear Antiferromagnets
Yun-Mei Li, Xi-Wang Luo, Kai Chang
Thermal fluctuation in magnets will bring temperature-dependent self-energy corrections to the magnons, however, their effects on the topological orders of magnons is not well expl…
Magnon Nernst Effect in Magnon Spin Hall Systems
Yun-Mei Li
Magnon spin Hall systems could hardly show experimentally observable particle and thermal transport phenomena intrinsically due to the spin cancellation. Here we demonstrated that…
Higher-order Topological Phases of Magnons in van der Waals Honeycomb Ferromagnets
Yun-Mei Li, Ya-Jie Wu, Xi-Wang Luo +2
We theoretically propose a second-order topological magnon insulator by stacking the van der Waals honeycomb ferromagnets with antiferromagnetic interlayer coupling. The system exh…
