Non-perturbative renormalization group in a hierarchical Kondo model

Rutgers University, USA

September 03, 2015


In this seminar, a hierarchical version of the Kondo model is introduced and shown to be exactly solvable via renormalization group techniques. The qualitative behavior of the magnetic susceptibility of the system is shown to be governed by a non-trivial fixed point in the renormalization group flow. The hierarchical Kondo model therefore provides an example of a system that can be studied exactly using renormalization group methods without being asymptotically free.

Joint work with Giuseppe Benfatto and Giovanni Gallavotti.
