Measurement-based quantum computation in finite one-dimensional systems: string order implies computational power
Robert Raussendorf, Wang Yang, Arnab Adhikary
We present a new framework for assessing the power of measurement-based quantum computation (MBQC) on short-range entangled symmetric resource states, in spatial dimension one. It…
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…
Counter-rotating spiral, zigzag, and 120 orders from coupled-chain analysis of Kitaev-Gamma-Heisenberg model, and relations to honeycomb iridates
Wang Yang, Alberto Nocera, Chao Xu +2
We study the nearest neighboring spin-1/2 Kitaev-Heisenberg-Gamma () model on the honeycomb lattice in the parameter region of ferromagnetic (FM) Kitaev and antiferromagnetic…
Spin Manipulation by Giant Valley-Zeeman Spin-Orbit Field in Atom-Thick WSe2
Xinhe Wang, Wei Yang, Wang Yang +6
The phenomenon originating from spin-orbit coupling (SOC) provides energy-efficient strategies for spin manipulation and device applications. The broken inversion symmetry interfac…
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…
Origin of nonsymmorphic bosonization formulas in generalized antiferromagnetic Kitaev spin- chains from a renormalization-group perspective
Wang Yang, Chao Xu, Alberto Nocera +1
Recently, in the Luttinger liquid phase of the one-dimensional generalized antiferromagnetic Kitaev spin-1/2 model, it has been found that the abelian bosonization formulas of the…

Symmetry analysis of bond-alternating Kitaev spin chains and ladders
Wang Yang, Alberto Nocera, Paul Herringer +2
In this work, we analyze the nonsymmorphic symmetry group structures for a variety of generalized Kitaev spin chains and ladders with bond alternations, including Kitaev-Gamma chai…
