Band Unfolding via the Quadratic Pseudospectrum
Christopher A. Bairnsfather, Ralph M. Kaufmann, Terry A. Loring +1
Band theory provides the foundation for understanding electronic structure in crystalline materials, but its reliance on exact translational symmetry limits its applicability to sy…
Nonabelian elastic metamaterials using holonomies acquired by crossing degeneracies
Mohit Kumar, Ralph M. Kaufmann, Fabio Semperlotti
Embedding nonabelian features into elastic metamaterials promises remarkable opportunities for wave control in many practical applications such as surface acoustic wave devices, mo…
Quantum Phase diagrams and transitions for Chern topological insulators
Ralph M. Kaufmann, Mohamad Mousa, Birgit Wehefritz-Kaufmann
Topological invariants such as Chern classes are by now a standard way to classify topological phases. Introducing and varying parameters in such systems leads to phase diagrams, w…
Refined Phase Diagram for a Spin-1 System Exhibiting a Haldane Phase
Mohamad Mousa, Birgit Wehefritz-Kaufmann, Sabre Kais +2
We provide the phase diagram of a 2-parameter spin-1 chain that has a symmetry-protected topological (SPT) Haldane phase using computational algorithms along with tensor-network to…
