0 Strong Coupling Approach to the Supersymmetric Kondo Model
We carry out the strong coupling expansion for the SU (N) Kondo model where the impurity spin is represented by a L-shaped Young tableau. Using second order perturbation theory around the strong coupling fixed point it is shown that when the antisymmetric component of the Young-tableau contains more than N/2 entries, the strong-coupling fixed point becomes unstable to a two-stage Kondo effect. ...

متن کاملThe Kondo lattice model from strong-coupling viewpoint
We study the magnetic excitation spectrum of the two-dimensional (2D) squarelattice S=1/2 Kondo lattice model at finite (hole) doping, by representing the Hamiltonian in terms of a set of local excitations. The location of the paramagneticantiferromagnetic phase boundary at T=0 is determined.
متن کاملStrong coupling limit of Bethe Ansatz equations
We develop a method to analyze the strong coupling limit of the Bethe ansatz equations supposed to give the spectrum of anomalous dimensions of the planar N = 4 gauge theory. This method is particularly adapted for the three rank-one sectors, su(2), su(1|1) and sl(2). We use the elliptic parametrization of the Bethe ansatz variables, which degenerates to a hyperbolic one in the strong coupling ...
