Topologically protected states in the Lieb lattice
In this thesis, we study the di erent types of boundary modes found in Lieb-type tight-binding Hamiltonians (of chains, ribbons and square clusters) that are strongly dependent on the symmetries present in the lattice. A new topological description is developed, with the aim of predicting the behavi...
