Abstract
We prove a Lifshitz tail bound on the integrated density of states of random breather Schr\"odinger operators. The potential is composed of translated single site potentials. The single site potential is an indicator function of set where is from the unit interval and is a measurable set contained in the unit cell. The challenges of this model are: Since is not assumed to be star-shaped the dependence of the potential on the parameter is not monotone. It is also non-linear and not differentiable.
