| 中文摘要 | By constructing the reflection Dunkl operator we derive several integrable models consisting of a boundary impurity coupled to an electron gas with interactions of the Calogero-Sutherland type. Some of these models were constucted previously using Lax-pair operators. The necessary condition of integrability imposes that the impurity potential has a form similar to that of the bulk interactions. Based on these results we conjecture that a Kondo impurity coupled to the host with long-range interactions of the l/r(2) type is also integrable. Using the asymptotic Bethe Ansatz we show that there are no Kondo logarithms, and depending on the coupling of the impurity to the host, the impurity spin can either be totally screened, partially screened, or unscreened. On the other hand, for a l/sinh(2)(r) interaction potential a Kondo effect with logarithms is obtained. |
