Singlet-triplet excitations and long range entanglement in the spin-orbital liquid candidate FeSc2S4

N. J. Laurita, J. Deisenhofer, LiDong Pan +6

Theoretical models of the spin-orbital liquid (SOL) FeSc${}_2$S${}_4$ have predicted it to be in close proximity to a quantum critical point separating a spin-orbital liquid phase from…
