Abstract
In this paper, we found a new type of insulator - composite spin liquid which can be regarded as a short range B-type topological spin-density-wave. Composite spin liquid is topological ordered state beyond the classification of traditional spin liquid states. The elementary excitations are the "composite electrons" with both spin degree of freedom and charge degree of freedom, together with topological spin texture. This topological state supports chiral edge mode but no topological degeneracy.
