The range of non-Kitaev terms and fractional particles in α-RuCl3
The range of non-Kitaev terms and fractional particles in α-RuCl3
Significant efforts have focused on the magnetic excitations of relativistic Mott insulators, predicted to realize the Kitaev quantum spin liquid (QSL). This exactly solvable model involves a highly entangled state resulting from bond-dependent Ising interactions that produce excitations which are non-local in terms of spin flips. A key challenge in …
