Let , be a strongly Lipschitz domain in and a magnetic Schr?dinger operator on satisfying the Dirichlet boundary condition, where and . In this paper, the authors introduce the Hardy space by the Lusin area function associated with and establish its equivalent characterization via the non-tangential maximal function associated with . As applications, the authors obtain the boundedness of the Riesz transforms , , from to for and the fractional integral from to for and , where is the closure of in .
