Low energy properties of the random displacement model
Jeff Baker, Michael Loss, Günter Stolz
We study low-energy properties of the random displacement model, a random Schrödinger operator describing an electron in a randomly deformed lattice. All periodic displacement conf…

Minimizing the ground state energy of an electron in a randomly deformed lattice
Jeff Baker, Michael Loss, Günter Stolz
We provide a characterization of the spectral minimum for a random Schrödinger operator of the form in , where the single site potent…
