Kondo effect in a Luttinger liquid: A boundary-conformal-field-theory approach

The Kondo problem in a Luttinger liquid has been studied recently using a poor-man{close_quote}s-scaling method. Here, the problem is formulated using the recent boundary-conformal-field-theory technique, which allows us to describe the critical points exactly. We recover the results for the specific heat and susceptibility calculated for low temperatures. {copyright} {ital 1996 The American Physical Society.}
