摘要：

The role of the Chern-Simons action in the description of the quantum Hall effect is stressed. The 2D electromagnetic picture of Widom and Srivastava is shown to be valid in a superlattice of 2D electron gases. A Meissner-like effect appears in such systems. In them, the difference between the external and the integer filling factor fields is exponentially screened by the surface (edge) currents. Also, effective Maxwell equations for one sheet or a superlattice are obtained. © 1990.
