Abelian bosonization approach to quantum impurity problems
Jinwu Ye
Using Abelian Bosonization, we develop a simple and powerful method to calculate the correlation functions of the two channel Kondo model and its variants. The method can also be u…
Solution of effective Hamiltonian of impurity hopping between two sites in a metal
Jinwu Ye
We analyze in detail all the possible fixed points of the effective Hamiltonian of a non-magnetic impurity hopping between two sites in a metal obtained by Moustakas and Fisher(MF)…
Solution of two channel spin-flavor Kondo model
Jinwu Ye
We investigate a model where an impurity couples to both the spin and the flavor currents of the two channel conduction electrons. This model can be used as a prototype model of a…
On two channel flavor anisotropic and one channel compactified Kondo models
Jinwu Ye
We reinvestigate the two channel flavor anisotropic model (2CFAK) and one channel compacitified Kondo model (1CCK). For these two models, all the possible fixed points and their sy…
