  We study the effect of anisotropy on holographic entanglement entropy (HEE)
and holographic mutual information (MI) in the Q-lattice model, by exploring
the HEE and MI for infinite strips along arbitrary directions. We find that the
lattice always enhances the HEE. The MI, however, is enhanced by lattice for
large sub-regions; while for small sub-regions, the MI is suppressed by the
lattice. We also discuss how these phenomena result from the deformation of
geometry caused by Q-lattices.
