摘要：
In this study, we consider a quantum waveguide with random boundary conditions . Precisely we consider Laplace operator restricted to a two dimensional straight strip of width d. We consider Dirchilet boundary condition on y = 0, while on y = d we consider mixed, Dirchilet and Neumann boundary condition in a random way. We prove that the integrated density of states of the relevant operator exhibits Lifshitz behavior at the bottom of the spectrum.
