     A primer on integrable techniques for 1D quantum systems


      Fabio Franchini
      IRB, Zavod za teorijsku fiziku

   Sažetak:

   One dimensional systems are intrinsically strongly interacting and  
require approaches beyond perturbation theory to be described. Some  
such models are known to be integrable and have paved the way to  
understand the universality of general low-dimensional systems. In  
this series of lectures I will present the basic ideas behind Bethe  
Ansatz integrability, through the example of the 1D Heisenberg chain  
and the XXZ chain. In the first two lectures I will introduce the  
model and the technique and use the coordinate Bethe Ansatz to  
construct the phase diagram of the model and discuss its low-energy  
excitations. In the third lecture I'll make a detour by solving a 2D  
classical statistical model, the six-vertex model, because its  
solution justifies the Algebraic Bethe Ansatz (ABA) techniques to  
solve the Heisenberg chain that will be the topic of the forth  
lecture. ABA overcomes the shortcomings of the coordinate approach and  
truly shows what is the nature of quantum integrability.
