Deep Learning of Phase Transitions for Bilinear-Biquadratic Spin-1 Chains from Correlation Aspects

Ming-Chiang Chung, Yu-Ting Kuo, Ian McCulloch +1

We investigate the role of different correlation functions in reconstructing the phase diagram of the spin-1 bilinear-biquadratic chain, parametrized by the angle $\theta$ between the b…
