Finite Size Scaling at the Topological Transition: Bilinear-Biquadratic Spin-1 Chain

21 Jun 2020 Wang Yuting Zhang Hao Kamenev Alex

We consider a finite size scaling function across a topological phase transition in 1D models. For models of non-interacting fermions it was shown to be universal for all topological symmetry classes and markedly asymmetric between trivial and topological sides of the transition (Gulden et al 2016)...
