Two-dimensional Spin Ice and the Sixteen-Vertex Model
In this thesis we present a thorough study of the static and dynamic properties of the 2D sixteen-vertex model or, in other words, a simplified version of the dipolar... -
Classification of sub-Riemannian Lie algebras and integrability of associated...
In this thesis, we are interested first in the sub-Riemannian problems on 2-step nilpotent Lie groups. We start by obtaining a complete classification of 2-step... -
