Non-Loudon-Fleury Raman scattering in spin-orbit coupled Mott insulators
Yang Yang, Mengqun Li, Ioannis Rousochatzakis +1
We revisit the theory of magnetic Raman scattering in Mott insulators with strong spin-orbit coupling, with a major focus on Kitaev materials. We show that Kitaev materials with bo…
Magnon-spinon dichotomy in the Kitaev hyperhoneycomb -LiIrO
Alejandro Ruiz, Nicholas P. Breznay, Mengqun Li +16
The family of edge-sharing tri-coordinated iridates and ruthenates has emerged in recent years as a major platform for Kitaev spin liquid physics, where spins fractionalize into em…
Reentrant incommensurate order and anomalous magnetic torque in the Kitaev magnet -
Mengqun Li, Ioannis Rousochatzakis, Natalia B. Perkins
We present a theoretical study of the response of - under external magnetic fields in the , and crystallographic planes. The results are b…
Unconventional magnetic field response of the hyperhoneycomb Kitaev magnet
Mengqun Li, Ioannis Rousochatzakis, Natalia B. Perkins
We present a unified description of the response of the hyperhoneycomb Kitaev magnet - to applied magnetic fields along the orthorhombic directions ${\b…
Collective spin dynamics of Z2 vortex crystals in triangular Kitaev-Heisenberg antiferromagnets
Mengqun Li, Natalia B. Perkins, Ioannis Rousochatzakis
We show that the mesoscopic incommensurate vortex crystals proposed for layered triangular anisotropic magnets can be most saliently identified by two distinctive si…
