Many-Body Quantum Zeno Effect and Measurement-Induced Subradiance Transition [PDF]
Quantum, 2021 It is well known that by repeatedly measuring a quantum system it is possible to completely freeze its dynamics into a well defined state, a signature of the quantum Zeno effect.

Storing Light with Subradiant Correlations in Arrays of Atoms [PDF]
Physical Review Letters, 2016 We show how strong light-mediated resonant dipole-dipole interactions between atoms can be utilized in a control and storage of light. The method is based on a high-fidelity preparation of a collective atomic excitation in a single correlated subradiant eigenmode in a lattice.

Super/subradiant second harmonic generation [PDF]
Laser Physics Letters, 2017 A scheme for active second harmonics generation is suggested. The system comprises $N$ three-level atoms in ladder configuration, situated into resonant cavity. It is found that the system can lase in either superradiant or subradiant regime, depending on the number of atoms $N$.

Fluorescence dynamics of an ensemble of cold atoms [PDF]
EPJ Web of Conferences, 2019 We have calculated the fluorescence dynamics of cold atoms excited by pulsed radiation. We have considered both Radon-Nikodym spectral method and multi-stage relaxation model describing collective effects in cold atomic gases.

Mean-Field Description of Cooperative Scattering by Atomic Clouds
Atoms, 2023 We present analytic expressions for the scattering of light by an extended atomic cloud. We obtain the solution for the mean-field excitation of different atomic spherical distributions driven by a uniform laser, including the initial build up, the ...

Stability and decay of subradiant patterns in a quantum gas with photon-mediated interactions. [PDF]
Sci AdvThe phenomenon of subradiance, marked by its surprising suppression of spontaneous emission, challenges conventional expectations of the collective behavior of scatterers.

Subradiant Bell States in Distant Atomic Arrays [PDF]
Physical Review Letters, 2019 We study collective `free-space' radiation properties of two distant single-layer arrays of quantum emitters as two-level atoms. We show that this system can support a long-lived Bell superposition state of atomic excitations exhibiting strong subradiance, which corresponds to a non-local excitation of the two arrays.

New Journal of Physics, 2022 Recent experimental advances enable the fabrication of photonic lattices in which the light propagates with engineered energy dispersions. When interfaced with quantum emitters, such systems yield strong collective spontaneous emission phenomena, such as

The Emergence of Subradiance in Ensembles of Quantum Optical Emitters
, 2023 Several of the leading quantum technologies are built around harnessing the intrinsic dynamics and interactions between single atoms. One of the key characteristics of these elementary building blocks is their spontaneous decay rate, which quantifies the
