Completely Subradiant Multi‐Atom Architectures Through 2D Photonic Crystals [PDF]
Annalen der Physik, 2018 AbstractFollowing recent advances in the manipulation of atoms trapped near 1D waveguides and proposals to use surface acoustic waves on piezoelectric substrates for the same purpose, the potential of two‐dimensional platforms is shown. Directional emission of atoms near photonic crystal slabs with square symmetry is used, in the ideal case, to build ...

Subradiant Decay in 2D and 3D Atomic Arrays
PhotonicsSubradiance is a phenomenon where coupled emitters radiate light at a slower rate than independent ones. While its observation was first reported in disordered cold atom clouds, ordered subwavelength arrays of emitters have emerged as promising platforms

Superradiant to subradiant phase transition in the open system Dicke model: dark state cascades
New Journal of Physics, 2018 Collectivity in ensembles of atoms gives rise to effects like super- and subradiance. While superradiance is well studied and experimentally accessible, subradiance remains elusive since it is difficult to track experimentally as well as theoretically ...

Multimode cold-damping optomechanics with delayed feedback
Physical Review Research, 2020 We investigate the role of time delay in cold-damping optomechanics with multiple mechanical resonances. For instantaneous electronic response, it was recently shown by C. Sommer and C. Genes [Phys. Rev. Lett.

Competition between finite-size effects and dipole-dipole interactions in few-atom systems
, 2016 In this paper, we study the competition between finite-size effects (i.e. discernibility of particles) and dipole-dipole interactions in few-atom systems coupled to the electromagnetic field in vacuum.

Strong interactions and subradiance in disordered metamaterials [PDF]
Physical Review B, 2018 We provide detailed comparisons between experimental findings and numerical simulations of large coopera- tively interacting, spatially disordered metamaterial arrays, consisting of asymmetrically split rings. Simulation methods fully incorporate strong field-mediated inter-meta-atom interactions between discrete resonators and statistical properties ...

Tuning the collective decay of two entangled emitters by means of a nearby surface
, 2017 We consider the radiative properties of a system of two identical correlated atoms interacting with the electromagnetic field in its vacuum state in the presence of a generic dielectric environment.

Quantum emitters coupled to surface plasmons of a nano-wire: A Green function approach
, 2010 We investigate a system consisting of a single, as well as two emitters strongly coupled to surface plasmon modes of a nano-wire using a Green function approach.

Induced dipole-dipole interactions in light diffusion from point dipoles
, 2016 We develop a perturbative treatment of induced dipole-dipole interactions in the diffusive transport of electromagnetic waves through disordered atomic clouds. The approach is exact at order two in the atomic density and accounts for the vector character
