Renormalization group analysis for bosonization coefficients in half-odd-integer Kitaev spin chains

Jianxun Li, Chao Xu, Wang Yang

Based on a renormalization-group (RG) analysis, we study the bosonization formulas for spin-$S$ Kitaev-Gamma and Kitaev-Heisenberg-Gamma chains in the parameter regime $K<0$, $\Gamma >0$…
