چکیده

We show how to resolve coherent low-energy features embedded in a broad high-energy background by use of a fully self-consistent calculation for composite particle operators. The method generalizes the formulation of Roth, which linearizes the dynamics of composite operators at any energy scale. Self-consistent equations are derived and analyzed in the case of the single-impurity SU(N) Kondo model.

نظریه میدان ناجابه‌جایی و پارامترهای نقض لورنتس در QED

Non-commutative field theory as a theory including the Lorentz violation can be constructed in two different ways. In the first method, the non-commutative fields are the same as the ordinary ones while the gauge group is restricted to U(n). For example, the symmetry group of standard model in non-commutative space is U(3)×(2)×U(1) which can be reduced to SU(3)×SU(2)×U(1) by two appropriate spo...

A local moment approach to the degenerate Anderson impurity model.

The local moment approach is extended to the orbitally degenerate (SU(2N)) Anderson impurity model (AIM). Single-particle dynamics are obtained over the full range of energy scales, focusing on particle-hole symmetry in the strongly-correlated regime where the onsite Coulomb interaction leads to many-body Kondo physics with entangled spin and orbital degrees of freedom. The approach captures ma...

Overscreened multichannel SU„N... Kondo model: Large-N solution and conformal field theory

The multichannel Kondo model with SU(N) spin symmetry and SU(K) channel symmetry is considered. The impurity spin is chosen to transform as an antisymmetric representation of SU(N), corresponding to a fixed number of Abrikosov fermions (a f a † f a5Q . For more than one channel (K.1), and all values of N and Q , the model displays non-Fermi behavior associated with the overscreening of the impu...

Reflection Factors for the Principal Chiral Model

We consider the SU (2) Principal Chiral Model (at level k = 1) on the half-line with scale invariant boundary conditions. By looking at the IR limiting confor-mal field theory and comparing with the Kondo problem, we propose the set of permissible boundary conditions and the corresponding reflection factors.

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. ...
