Subradiance-protected excitation transport
Jemma A. Needham, Igor Lesanovsky, Beatriz Olmos
We explore excitation transport within a one-dimensional chain of atoms where the atomic transition dipoles are coupled to the free radiation field. When the atoms are separated by…

Modified dipole-dipole interaction and dissipation in an atomic ensemble near surfaces
Ryan Jones, Jemma A. Needham, Igor Lesanovsky +2
We study how the radiative properties of a dense ensemble of atoms can be modified when they are placed near or between metallic or dielectric surfaces. If the average separation b…
