The paper continues the development of the rigorous supersymmetric transfer matrix approach to the random band matrices started in (J Stat Phys 164:1233–1260, 2016; Commun Math Phys 351:1009–1044, 2017). We consider random Hermitian block band matrices consisting ofrandom Gaussian blocks (parametrized by) with a fixed entry’s variance,in each block. Taking the limitwith fixednand, we derive the sigma-model approximation of the second correlation function similar to Efetov’s one. Then, considering the limit, we prove that in the dimensionthe behaviour of the sigma-model approximation in the bulk of the spectrum, as, is determined by the classical Wigner–Dyson statistics.
