Semimetal with both Rarita-Schwinger-Weyl and Weyl excitations
Long Liang, Yue Yu
A relativistic spinor with spin 3/2 is historically called Rarita-Schwinger spinor. The right- and left-handed chiral degrees of freedom for the massless Rarita-Schwinger spinor ar…
Topological phase transitions in the repulsively interacting Haldane-Hubbard model
Tuomas I. Vanhala, Topi Siro, Long Liang +3
Using dynamical mean-field theory and exact diagonalization we study the phase diagram of the repulsive Haldane-Hubbard model, varying the interaction strength and the sublattice p…
Rarita-Schwinger-Weyl semimetal in Jeff=3/2 electron systems
Long Liang, Yue Yu
We propose a relativistic Jeff=3/2 semimetal with 4d1 or 5d1 electrons on a cubic lattice when the strong spin-orbital coupling takes over the Hunds' coupling. A relativistic spino…
Global Phase Diagram of the Extended Kitaev-Heisenberg Model on Honeycomb Lattice
Jie Lou, Long Liang, Yue Yu +1
We study the extended Kitaev-Heisenberg (EKH) quantum spin model by adding bond-dependent off-diagonal Heisenberg term into the original KH model, which was recently proposed to de…
