In two dimensions, topologically ordered phases defined on a nontrivial manifold have degenerate ground states protected by a gap. However, it has been a nontrivial task to find these states in physically relevant microscopic Hamiltonians. In this talk I will discuss our progress on hunting for topologically ordered states with tensor network methods. The emphasis will be given to our recent result on the spin-1/2 kagome Heisenberg antiferromagnet, for which we provide strong evidence that its ground state is a chiral spin liquid with spontaneously broken time-reversal symmetry.
