Rigorous Solution of the Spin-1 Quantum Ising Model with Single-ion Anisotropy

Zhihua Yang, Liping Yang, Jianhui Dai +1

We solve the spin-1 quantum Ising model with single-ion anisotropy by mapping it onto a series of segmented spin-1/2 transverse Ising chains, separated by the $S^z=0$ states calle…
