Possible coexistence of short-range resonating-valence-bond and long-range stripe correlations in the spatially anisotropic triangular-lattice quantum magnet Cu(OH)NO
Long Yuan, Yuqian Zhao, Boqiang Li +5
We show that short-range resonating-valence-bond correlations and long-range order can coexist in the ground state (GS) of a frustrated spin system. Our study comprises a comprehen…
Evidence for a gapless Dirac spin-liquid ground state in a spin-3/2 triangular-lattice antiferromagnet
Jiabin Liu, Benqiong Liu, Long Yuan +8
We report a comprehensive investigation of the magnetism of the = 3/2 triangular-lattice antiferromagnet, -CrOOH(D) (delafossites green-grey powder). The nearly Heisenberg a…
Rearrangement of uncorrelated valence bonds evidenced by low-energy spin excitations in YbMgGaO4
Yuesheng Li, Sebastian Bachus, Benqiong Liu +6
DC-magnetization data measured down to 40 mK speak against conventional freezing and reinstate YbMgGaO as a triangular spin-liquid candidate. Magnetic susceptibility measured p…
Magnetoelastic hybrid excitations in CeAuAl
Petr Čermák, Astrid Schneidewind, Benqiong Liu +5
The interactions between elementary excitations such as phonons, plasmons, magnons, or particle-hole pairs, drive emergent functionalities and electronic instabilities such as mult…
Structural instabilities and mechanical properties of UMo from first principles calculations
Ben-Qiong Liu, Xiao-Xi Duan, Guang-Ai Sun +2
We perform detailed first principles calculations of the structural parameters at zero pressure and high pressure, the elastic properties, phonon dispersion relation, and ideal str…
Quantum correlations in bulk properties of solids obtained from neutron scattering
Ben-Qiong Liu, Lian-Ao Wu, Guo-Mo Zeng +6
We demonstrate that inelastic neutron scattering technique can be used to indirectly detect and measure the macroscopic quantum correlations quantified by both entanglement and dis…
General Quantum State Swap: an XY model analysis
Ben-Qiong Liu, Lian-Ao Wu, Bin Shao +1
We consider an exact state swap, defined as the swap between two quantum states |A> and |B> in the Hilbert space of a quantum system. We show that, given an arbitrary Hamiltonian d…
Quantum and classical correlations in the one-dimensional XY model with Dzyaloshinskii-Moriya interaction
Ben-Qiong Liu, Bin Shao, Jun-Gang Li +2
We study the effect of Dzyaloshinskii-Moriya (DM) interaction on pairwise quantum discord, entanglement, and classical correlation in the anisotropic XY spin-half chain. Analytical…
