In this paper we consider vector-valued Schrödinger operators of the form div(Q∇ u)-Vu, where V=(vij) is a nonnegative locally bounded matrix-valued function and Q is a symmetric, strictly elliptic matrix whose entries are bounded and continuously differentiable with bounded derivatives. Concerning the potential V, we assume an that it is pointwise accretive and that its entries are in L^∞loc(ℝd). Under these assumptions, we prove that a realization of the vector-valued Schrödinger operator generates a C0-semigroup of contractions in Lp(ℝd; ℂm). Further properties are also investigated.
