The spectrum of local random Hamiltonians


Abstract The spectrum of a local random Hamiltonian can be represented generically by the so-called epsilon-free convolution of the probability distributions of its local terms. We establish an isomorphism between the set of epsilon-noncrossing partitions and permutations to study its spectrum. Moreover, we derive some lower and upper bounds for the maximal eigenvalue of the Hamiltonian.
