摘要：
We discuss, by making use of symmetric property of a system, a second order optical response which characterizes surface magnetism appeared on a Kagome quantum dot array, whose origin is electronic band flatness. We also explore characteristic properties of the excitons created on the Kagome lattice, and linear and nonlinear optical responses by using pseudospin operators. (C) 2002 Elsevier Science B.V.
