Dynamics of transport by helical edge states
Luis Alberto Razo López, Pierre Wulles, Geoffroy J. Aubry +2
Topologically nontrivial band structure of a material may give rise to special states that are confined to the material's boundary and protected against disorder and scattering. Qu…
Topological photonic band gaps in honeycomb atomic arrays
Pierre Wulles, Sergey E. Skipetrov
The spectrum of excitations a two-dimensional, planar honeycomb lattice of two-level atoms coupled by the in-plane electromagnetic field may exhibit band gaps that can be opened ei…
Photonic topological Anderson insulator in a two-dimensional atomic lattice
Sergey E. Skipetrov, Pierre Wulles
Disorder in atomic positions can induce a topologically nontrivial phase - topological Anderson insulator (TAI) - for transverse electric optical quasimodes of a two-dimensional ho…
Topological transitions and Anderson localization of light in disordered atomic arrays
S. E. Skipetrov, P. Wulles
We explore the interplay of disorder and topological phenomena in honeycomb lattices of atoms coupled by the electromagnetic field. On the one hand, disorder can trigger transition…
