We study spatially periodic logarithmic Schrödinger equations: LS {&-Δ u+ V (x) u= Q (x) u\log u^ 2,\quad u> 0\quad in\mathbb R^ N,\&u ∈ H^ 1 (R^ N),.-Δ u+ V (x) u= Q (x) u log u 2, u> 0 in RN, u∈ H 1 (RN), where N ≥ 1 N≥ 1 and V (x), Q (x) are spatially 1-periodic functions of class C^ 1 C 1. We take an approach using spatially 2 L-periodic problems (L ≫ 1 L≫ 1) and we show the existence of infinitely many multi-bump solutions of (LS) which are distinct under Z^ N ZN-action.
