Engineering symmetry-protected topological states in waveguide arrays
Lavi K. Upreti
The topological classification of a system depends on the discrete symmetries of its Hamiltonian. In Floquet photonic waveguide arrays, the abstract symmetries of the Altland--Zirn…

Topological properties of Floquet winding bands in a photonic lattice
Albert F. Adiyatullin, Lavi K. Upreti, Corentin Lechevalier +6
The engineering of synthetic materials characterised by more than one class of topological invariants is one of the current challenges of solid-state based and synthetic materials.…
