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 in spin- Kitaev-Gamma and Kitaev-Heisenberg-Gamma chains in the parameter reg…
Many-body wave function and edge magnetization of an open superconducting chain
Jiarui Jiao, Chao Xu, Congjun Wu +1
Although BCS wave functions for superconductors under periodic boundary conditions are well established, obtaining an explicit form of the many-body BCS wave function under open bo…
Left-left-right-right magnetic order in spin-1/2 Kitaev-Heisenberg chain
Wang Yang, Chao Xu, Shicheng Ma +2
In this work, we perform a combination of analytical and numerical studies on the phase diagram of the spin-1/2 Kitaev-Heisenberg chain in the region of negative Kitaev and positiv…
Emergent SU(2) conformal symmetry in the spin-1/2 Kitaev-Gamma chain with a Dzyaloshinskii-Moriya interaction
Wang Yang, Alberto Nocera, Chao Xu +3
We study the one-dimensional spin-1/2 Kitaev-Gamma model with a bond-dependent Dzyaloshinskii-Moriya (DM) interaction, which can be induced by an electric field applied in the thir…
Nonsymmorphic spin-space cubic groups and SU(2) conformal invariance in one-dimensional spin-1/2 models
Wang Yang, Alberto Nocera, Chao Xu +1
Recently, extended gapless phases with emergent SU(2) conformal invariance occupying finite regions in the phase diagrams have been found in one-dimensional spin-1/2 models wit…
