TY - JOUR ID - 1085330 AU - Oles, Andrzej M. - Chaloupka, Jiří PY - 2012 TI - Spin-Orbital Liquid on a Triangular Lattice JF - Acta physica polonica A VL - 121 IS - 5-6 SP - 1026-1028 EP - 1026-1028 PB - POLISH ACAD SCIENCES INST PHYSICS SN - 05874246 KW - spin-orbital liquid KW - entangled valence bond states KW - exact diagonalization N2 - Using Lanczos exact diagonalization of finite clusters we demonstrate that the spin-orbital d(1) model for triply degenerate t(2g) orbitals on a triangular lattice provides an example of a spin-orbital liquid ground state. We also show that the spin-orbital liquid involves entangled valence bond states which violate the Goodenough-Kanamori rules, and modify effective spin exchange constants. ER -
