Fractional and composite excitations of antiferromagnetic quantum spin trimer chains
Jun-Qing Cheng, Jun Li, Zijian Xiong +3
Using quantum Monte Carlo, exact diagonalization and perturbation theory, we study the spectrum of the antiferromagnetic Heisenberg trimer chain by varying the ratio $g=J_2…
Electronic structure, magnetism and high-temperature superconductivity in the multi-layer octagraphene and octagraphite
Jun Li, Shangjian Jin, Fan Yang +1
We systematically investigate the electronic structure, magnetism and high-temperature superconductivity (SC) in the multi-layer octagraphene and octagraphite (bulk octagraphene).…
Exact diagonalization study of the anisotropic Heisenberg model related to YbMgGaO
Muwei Wu, Dao-Xin Yao, Han-Qing Wu
Employing exact diagonalization, we systematically study the anisotropic Heisenberg model which is related to rare-earth triangular-lattice materials. We probe its full 3D phase di…
Torque equilibrium spin wave theory of Raman scattering in an anisotropic triangular lattice antiferromagnet with Dzyaloshinskii-Moriya interaction
Chao Shan, Shangjian Jin, Trinanjan Datta +1
We apply torque equilibrium spin wave theory (TESWT) to investigate an anisotropic XXZ antiferromagnetic model with Dzyaloshinskii-Moriya (DM) interaction in a triangular lattice.…
Triply degenerate nodal lines in topological and non-topological metals
Zhihai Liu, Luyang Wang, Dao-Xin Yao
Topological nodal-line semimetals exhibit double or fourfold degenerate nodal lines, which are protected by symmetries. Here, we investigate the possibility of the existence of tri…
Phonon dispersions and electronic structures of two-dimensional IV-V compounds
Wanxing Lin, Shi-Dong Liang, Jiesen Li +1
One novel family of two-dimensional IV-V compounds have been proposed, whose dynamical stabilities and electronic properties have been systematically investigated using the density…
