In this paper, we first consider the spectrum of the fractional Schrödinger operator (− Δ) s+ V (x) on R N, where s∈(0, 1) and V (x) be continuous, periodic in x. Using a new nonlocal normal derivative, we prove that the operator has purely continuous spectrum which is bounded below and consists of closed disjoint intervals. Then when 0 belongs to a spectral gap of (− Δ) s+ V (x), we establish an existence result for the fractional Schrödinger equation via a new linking theorem. It is worth to mention that the nonlinear term in our problem does not satisfy the periodicity and the existence result is even new for the case s= 1.
