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…
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…
Quantum versus classical effects in two-photon speckle patterns
Manutea Candé, Sergey E. Skipetrov
We discuss quantum and classical aspects of two-photon interference in light transmission through disordered media. We show that disorder is the main factor that suppresses the int…
Photon noise in a random laser amplifier with fluctuating properties
V. Yu. Fedorov, S. E. Skipetrov
We study fluctuations of the number of photocounts measured by an ideal photodetector illuminated by light scattered in an amplifying disordered medium, below the threshold for ran…
