 Given a sample of dimensions formula_35 and applying the periodic boundary conditions in the formula_31-direction formula_37 being formula_38 an integer, one gets that each parabolic potential is placed at a value formula_39.The number of states for each Landau Level and formula_23 can be calculated from the ratio between the total magnetic flux that passes through the sample and the magnetic flux corresponding to a state.Thus the density of states per unit surface is formula_42.
