We construct a new type of holographic correspondence between nonrelativistic string theory in string Newton-Cartan AdS5 × S5 and Galilean electrodynamics supplemented with five uncharged massless free scalar fields living on the 3+1 dimensional Penrose conformal boundary. In our derivation, we start with Maldacena’s setting of a stack of coincident D3-branes, and we show that the near-horizon/decoupling limit commutes with the nonrelativistic limit, giving a unique answer both from the gravity and gauge theory perspectives. As a first evidence, we systematically compute the Killing vectors on the string theory side, and find that they match the symmetries of the dual gauge theory.
