Photon-induced atom recoil in collectively interacting planar arrays

The recoil of atoms in arrays due to the emission or absorption photons is studied for subwavelength interatomic spacing. array interact with each other through collective dipole-dipole interactions and incident laser field low-intensity limit. Shining uniform light on gives rise patterns excitation array. They arise interference different eigenmodes excitation. relation between decay dynamics when its eigenstates. experienced by a subradiant substantially larger than that from independent atom decay. A method calculate rate steady state has been achieved constant influx also described.
