Supersymmetric spin operators
P. Coleman, C. Pepin, A. M. Tsvelik
We develop a supersymmetric representation of spin operators which unifies the Schwinger and Abrikosov representations of SU(N) spin operators, allowing a second-quantized treatmen…

Induced Luttinger Liquid Behavior in an Exactly Solvable Model of Stripes
Catherine Pepin, Alexei M. Tsvelik
We study an exactly solvable model describing a stripe consisting of a Toda array of anharmonic elastic chains sandwiched between two conducting chains. It is shown that the pr…

The Kondo Lattice Model
Mireille Lavagna, Catherine Pepin
In this lecture, we review the experimental situation of heavy Fermions with emphasis on the existence of a quantum phase transition (QPT) and related non-Fermi liquid (NFL) effect…
