“…This filling factor may take on integer values or fractional values and is described by both the electron density and the quantization of magnetic flux. When the filling factor takes on fractional values, this phenomenon is called the fractional quantum Hall effect, or, FQHE [9,19,27,32,38]. The model describing the FQHE in a two-dimensional doublelayered system was described with the use of Chern-Simons theory [3,13,17,18,22,28,30,35,36,39,40,[44][45][46][47].…”
