Topological classification of symmetric quantum walks. Discrete symmetry types and chiral symmetric protocols

Geib, Tobias (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2022)

In this thesis, we study the topological classification of symmetric quantum walks. These describe the discrete time evolution of single quantum particles on the lattice with additional locally acting symmetries. The thesis ...
Translation invariant quantum walks with discrete symmetries

Stahl, Christoph (Hannover : Institutionelles Repositorium der Leibniz Universität Hannover, 2018)

Quantum walks are discrete-time evolutions of single particles on lattices that transfer the concept of classical random walks to quantum theory. Topological insulators are objects that promise symmetry-protected edge-states ...
