Density of states for the $\pi$-flux state with bipartite real random hopping only: A weak disorder approach

C. Mudry, S. Ryu, A. Furusaki

Gade [R. Gade, Nucl. Phys. B \textbf{398}, 499 (1993)] has shown that the local density of states for a particle hopping on a two-dimensional bipartite lattice in the presence of w…
