Apparent double- $T_{c}$ from a single BKT transition in anisotropic phase-only models

Pei-Yuan Cai, Yi Zhou

Transport experiments on two-dimensional superconductors often yield direction-dependent transition temperatures, raising the question of whether such a ``double- $T_{c}$ '' reflects a…

Symmetry-protected topological order identified via Gutzwiller-guided density-matrix-renormalization-group: $SO (n)$ spin chains

Pei-Yuan Cai, Hui-Ke Jin, Yi Zhou

We present a comprehensive study of topological phases in the SO( $n$ ) spin chains using a combination of analytical parton construction and numerical techniques. For even $n = 2 l$ , w…
