Separability and entanglement in finite dimer-type chains in general transverse fields

We determine the conditions under which general dimer-type spin chains with XYZ couplings of arbitrary range in a general transverse field will exhibit an exactly separable parity-breaking eigenstate. We also provide sufficient conditions which ensure that it will be a ground state. We then examine...
