Subradiant spontaneous undulator emission through collective suppression of shot noise
Physical Review Special Topics. Accelerators and Beams, 2015 The phenomenon of Dicke’s subradiance, in which the collective properties of a system suppress radiation, has received broad interest in atomic physics.

Many-body subradiant excitations in metamaterial arrays: experiment and theory [PDF]
Physical Review Letters, 2017 Subradiant excitations, originally predicted by Dicke, have posed a long-standing challenge in physics owing to their weak radiative coupling to environment.

Subradiant Split Cooper Pairs [PDF]
Physical Review Letters, 2012 We suggest a way to characterize the coherence of the split Cooper pairs emitted by a double-quantum-dot based Cooper pair splitter (CPS), by studying the radiative response of such a CPS inside a microwave cavity. The coherence of the split pairs manifests in a strongly nonmonotonic variation of the emitted radiation as a function of the parameters ...

, 2022 Cooperative optical effects provide a pathway to both the amplification (superradiance) and the suppression (subradiance) of photon emission from electronically excited states.

Communication and the emergence of collective behavior in living organisms: a quantum approach. [PDF]
Mol Biol Int, 2013 Intermolecular interactions within living organisms have been found to occur not as individual independent events but as a part of a collective array of interconnected events. The problem of the emergence of this collective dynamics and of the correlated biocommunication therefore arises.

Polariton dynamics in one-dimensional arrays of atoms coupled to waveguides
New Journal of Physics, 2022 Photons strongly coupled to material systems constitute a novel system for realizing non-linear optics at the level of individual photons and studying the dynamics of non-equilibrium quantum many-body system.

Parity‐time symmetry and coherent perfect absorption in a cooperative atom response
Nanophotonics, Volume 10, Issue 4, Page 1357-1366, March 2021., 2021 Abstract Parity‐Time (PT) symmetry has become an important concept in the design of synthetic optical materials, with exotic functionalities such as unidirectional transport and nonreciprocal reflection. At exceptional points, this symmetry is spontaneously broken, and solutions transition from those with conserved intensity to exponential growth or ...

Optimal subradiant spin wave exchange in dipole-coupled atomic ring arrays
New Journal of Physics, 2023 The subwavelength array of quantum emitters provides an ideal platform for exploring rich many-body dynamics, such as super- and subradiance. In this paper, we explore the dynamics of spin wave exchange between two dipole-coupled atomic ring arrays ...
