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…
