Abstract

The Schrödinger difference operator considered here has the form {Mathematical expression} where V is a C²-periodic Morse function taking each value at not more than two points. It is shown that for sufficiently small e{open} the operator H_e{open}(α) has for a.e. α a pure point spectrum. The corresponding eigenfunctions decay exponentially outside a finite set. The integrated density of states is an incomplete devil's staircase with infinitely many flat pieces.
