Bond-dependent anisotropy and magnon decay in cobalt-based Kitaev triangular antiferromagnet
Chaebin Kim, Sujin Kim, Pyeongjae Park +9
The Kitaev model, a honeycomb network of spins with bond-dependent anisotropic interactions, is a rare example of having a quantum spin liquid ground state. Although most Kitaev mo…
Anisotropic magnon damping by zero-temperature quantum fluctuations in ferromagnetic CrGeTe
Lebing Chen, Chengjie Mao, Jae-Ho Chung +7
Spin and lattice are two fundamental degrees of freedom in a solid, and their fluctuations about the equilibrium values in a magnetic ordered crystalline lattice form quasiparticle…
