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- Kitaev-Gamma and Kitaev-Heisenberg-Gamma chains in the parameter regime , …
Left-left-right-right magnetic order in spin-1/2 Kitaev-Heisenberg chain
