We show the existence of a nonzero solution for the semilinear Schrödinger equation −∆u + V (x)u = f(x, u). The potential V is periodic and 0 belongs to a gap of σ(−∆ + V ). The function f is superlinear and asymptotically periodic with respect to x variable. In the proof we apply a new critical point theorem for strongly indefinite functionals proved in [3].
