Abstract
In this paper we show the that the ground state energy of the onedimensional discrete random Schrödinger operator with Bernoulli potential is controlled asymptotically as the system size N goes to infinity by the random variable ℓ N the length the longest consecutive sequence of sites on the lattice with potential equal to zero Specifically we will show that for almost every realization of the potential the ground state energy behaves asymptotically as fracpi2ell N +12 in the sense that the ratio of the quantities goes to oneWe would like to thank W Faris for the suggestion to look at potentials with Bernoulli distributions which turned out to be a great starting point We would like to thank R Sims for useful discussions in particular of the broader context of random Schrödinger operator theory We would like to thank M Lewenstein A Sanpera P Massignan and J Stasińska for collaborating with us on related projects as well as providing supporting numerical results The first idea of the present paper grew out of discussions with J Xin Both authors were supported in part by NSF grant DMS1009508 and M Bishop was in addition funded by NSF VIGRE grant DMS0602173 at the University of Arizona and by the NSF under Grant No DGE0841234
