1. The one-dimensional Kondo Lattice in the Majorana Fermion representation
Abstract : This thesis analyses the possibilities offered by the representation of quantum mechanical operators in terms of Majorana fermions. These objects can be imagined as algebraic constituents of the fermionic degrees of freedom, allowing for a different representation of many Hamiltonians. READ MORE
