RUI: Novel Transport Properties in Strongly Interacting Electron SystemsDonna Sheng, Cal. State Univ. Northridge Barry Friedman, Sam Houston State Univ., DMR 0307170 • We explore ground state, transport property and quantum phase transition from exact spectrum and topological property of wave-function. (a) (top left) Spin polorization in spin-orbit coupling graphene system with nontrivial Chern number. (b) (top right) Unconventional QHE in graphene. (c) (bottom) Superfluid density and diagonal order parameter demonstrate a super-solid phase. We also explain the phonon Hall effect discovered experimentally as associated with magnetization of ions.
