摘要：

We investigate a tight-binding model of the ruby lattice with Rashba spin-orbit coupling. We calculate the band structure of the lattice and evaluate the Z(2) topological indices. According to the Z(2) topological indices and the band structure, we present the phase diagrams of the lattice with different filling fractions. We find that topological insulators occur in some range of parameters at 1/6, 1/3,1/2,2/3 and 5/6 filling fractions. We analyze and discuss the characteristics of these topological insulators and their edge states.
