英文摘要 | We study the residue entropy of overscreen multi-channel kondo model by means of perturbative renormalization group. in this field theory framework one must use pseudofermion representation for local spin operator, and the constraint of pseudofermion must be treated properly we treat the constraint by a method developed recently in this method the partition function of the kondo model is separated into proper weighted partition functions of subsystems. we study the overscreen multi-channel kondo model through m-subsystem. from calculating the residue entropy of m-subsystem, we obtain the residue entropy of original system which agrees with the result of conformal field theory. |
