Observation of anisotropic dispersive dark exciton dynamics in CrSBr
J. Sears, B. Zager, W. He +15
Many-body excitons in CrSBr are attracting intense interest in view of their highly anisotropic magneto-optical coupling and their potential for novel optical interfaces within spi…

Dispersive dark excitons in van der Waals ferromagnet CrI3
W. He, J. Sears, F. Barantani +11
Spin-flip dark excitons are optical-dipole-forbidden quasiparticles with remarkable potential in optoelectronics, especially when they are realized within cleavable van der Waals m…

Topological Magnons on the Ferromagnetic Zigzag Lattice
Skandan Subramanian, Tom Berlijn, Lucas Lindsay +2
Motivated by the experimental identification of magnetic compounds consisting of zigzag chains, we analyze the band structure topology of magnons in ferromagnets on a zigzag lattic…
