Single photon subradiance and superradiance revisited: a group theoretic analysis of subradiant states

Physica Scripta, 2016
Single photon emission from a collection of resonantly excited two-level atoms is an expanding field. Recent work has shown single photon superradiance from an extended ensemble yields enhanced directional spontaneous emission. This paper presents an operator which commutes with the observables and breaks their degeneracy for the single photon states ...

Super- and Subradiant Lattice Resonances in Bipartite Nanoparticle Arrays

ACS Nano, 2020
Lattice resonances, the collective modes supported by periodic arrays of metallic nanoparticles, give rise to very strong and spectrally narrow optical responses. Thanks to these properties, which emerge from the coherent multiple scattering enabled by the periodic ordering of the array, lattice resonances are used in a variety of applications such as ...

Superradiance and subradiance in three-level systems

Optics Communications, 1980
Abstract Cooperative phenomena in spontaneous emission may exhibit two opposite features: either an increased emission rate, usually called superradiance, or a decreased emission rate, which we call subradiance. It is shown that, in a specific case of three-level atoms, symmetry considerations permit one to find realistic initial conditions such that

Superradiance and subradiance. III. Small samples

Journal of Physics B: Atomic and Molecular Physics, 1987
For pt.II see ibid., vol.19, p.2109 (1986). This paper is the third in a theoretical study of subradiance, i.e. the cooperative inhibition of spontaneous emission by a destructive interatomic interference, a phenomenon which has recently been observed.
