초록: Recently, the lattice structure has been studied in holographic models(1209.1098 ,1204.0519). We consider another model which contains metric, a maxwell field, and a complex scalar in AdS4. Since we use complex scalar, we may take probe limit and it makes computation simpler. Putting lattice structure to boundary configuration, we can construct partial differential equations. Solving the PDEs give us a lattice backgroud. Using this background, we try to find optical conductivity and compare the behavior to the result in 1209.1098.
