Coulomb Blockade in Hierarchical Quantum Hall Droplets
Andrea Cappelli, Lachezar S. Georgiev, Guillermo R. Zemba
The degeneracy of energy levels in a quantum dot of Hall fluid, leading to conductance peaks, can be readily derived from the partition functions of conformal field theory. Their c…

Mott transition and integrable lattice models in two dimensions
Federico L. Bottesi, Guillermo R. Zemba
We describe the two-dimensional Mott transition in a Hubbard-like model with nearest neighbors interactions based on a recent solution to the Zamolodchikov tetrahedron equation, wh…

Effective Field Theories for Electrons in Crystalline Structures
Federico L. Bottesi, Guillermo R. Zemba
We present an effective field theory formulation for a class of condensed matter systems with crystalline structures for which some of the discrete symmetries of the underlying cry…
