A bstract We study the properties of the Schrödinger-type non-relativistic holography for general dynamical exponent z with and without hyperscaling violation exponent θ . The scalar correlation function has a more general form due to general z as well as the presence of θ , whose effects also modify the scaling dimension of the scalar operator. We propose a prescription for minimal surfaces of this “codimension 2 holography”, and demonstrate the ( d − 1) dimensional area law for the entanglement entropy from ( d + 3) dimensional Schrödinger backgrounds. Surprisingly, the area law is violated for d + 1 < z < d + 2, even without hyperscaling violation, which interpolates between the logarithmic violation and extensive volume dependence of entanglement entropy. Similar violations are also found in the presence of the hyperscaling violation. Their dual field theories are expected to have novel phases for the parameter range, including Fermi surface. We also analyze string theory embeddings using non-relativistic branes.
