Partial Bergman kernels Πk,E are kernels of orthogonal projections onto subspaces Sk ⊂ H0 (M, Lk) of holomorphic sections of the kth power of an ample line bundle over a Kähler manifold (M, ω). The subspaces of this article are spectral subspaces {Ĥk ≤ E} of the Toeplitz quantization Ĥk of a smooth Hamiltonian H:M→R. It is shown that the relative partial density of states satisfies Πk,E(z)/Πk(z)→1A where A={H < E}. Moreover it is shown that this partial density of states exhibits “Erf” asymptotics along the interface ∂A; that is, the density profile asymptotically has a Gaussian error function shape interpolating between the values 1 and 0 of 1A. Such “Erf” asymptotics are a universal edge effect. The different types of scaling asymptotics are reminiscent of the law of large numbers and the central limit theorem.
