Subradiant Decay in 2D and 3D Atomic Arrays
Nicola Piovella, Romain Bachelard
Subradiance 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, or…

Subradiance generation in a chain of two-level atoms with a single excitation
Nicola Piovella
Studies of subradiance in a chain N two-level atoms in the single excitation regime focused mainly on the complex spectrum of the effective Hamiltonian, identifying subradiant eige…

Cooperative Decay of N Atoms in a Ring Configuration
Nicola Piovella
We provide an analytic expression of the spectrum of the cooperative decay rate of N two-level atoms regularly distributed on a ring in the single-excitation configuration. The res…
