Heisenberg spin chains with additional isotropic three-site exchange interactions
The J_1-J_3 Heisenberg spin models with nearest-neighbor (J_1) and additional isotropic three-site (J_3) spin interactions remain relatively less explored, although such types of competing exchange terms can naturally emerge from different sources, including the strong-coupling expansion of the mult...
