Divergences in resolvent expansion of Anderson hamiltonian
I'm reading these lecture notes on Anderson localization, and I cannot understand how the resonant regions contribute to the divergence of the resolvent expansion (sections 3.1 and 3.2). The relevant …

A quadratic Hamiltonian is a model of independent particles - why?
I'm reading some notes on the Anderson Hamiltonian:
$$ H=\sum h_i c_i^\dagger c_i -q\sum_{\langle i,j\rangle}(c_i^\dagger c_j+c_j^\dagger c_i)$$
Where the $c_i/c_i^\dagger$ are fermionic annihilation/ …
