Connecting steady-states of driven-dissipative photonic lattices with spontaneous collective emission phenomena

open access: yesNew 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

open access: yes, 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

From superradiance to subradiance: exploring the many-body Dicke ladder

open access: yes, 2021
We report a time-resolved study of collective emission in dense ensembles of two-level atoms. We compare, on the same sample, the build-up of superradiance and subradiance from the ensemble when driven by a strong laser.

Subradiant spontaneous undulator emission through collective suppression of shot noise

open access: yesPhysical 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.

Interpretable machine-learning identification of the crossover from subradiance to superradiance in an atomic array [PDF]

open access: yes, 2022
Light-matter interacting quantum systems manifest strong correlations that lead to distinct cooperative spontaneous emissions of subradiance or superradiance.

Subradiant states of quantum bits coupled to a one-dimensional waveguide

open access: yesNew Journal of Physics, 2019
The properties of coupled emitters can differ dramatically from those of their individual constituents. Canonical examples include sub- and super-radiance, wherein the decay rate of a collective excitation is reduced or enhanced due to correlated ...

Spatial Coherence of Light in Collective Spontaneous Emission

open access: yesPRX Quantum, 2022
When a quantum system is put into an excited state, it will decay back to the ground state through a process termed spontaneous emission. It is generally assumed that spontaneous emissions between different individual emitters will not be coherent with ...

Polarization control of radiation and energy flow in dipole-coupled nanorings

open access: yesNew Journal of Physics, 2020
Collective optical excitations in dipole-coupled nanorings of sub-wavelength spaced quantum emitters exhibit extreme sub-radiance and field confinement facilitating an efficient and low-loss ring-to-ring energy transfer.

Exact Markovian and non-Markovian time dynamics in waveguide QED: collective interactions, bound states in continuum, superradiance and subradiance [PDF]

open access: yesQuantum, 2019
We develop a formalism for modelling $exact$ time dynamics in waveguide quantum electrodynamics (QED) using the real-space approach. The formalism does not assume any specific configuration of emitters and allows the study of Markovian dynamics $\textit ...

Hybrid cavity‐antenna systems for quantum optics outside the cryostat?

open access: yesNanophotonics, Volume 8, Issue 9, Page 1513-1531, June 2018., 2018
Abstract Hybrid cavity‐antenna systems have been proposed to combine the sub‐wavelength light confinement of plasmonic antennas with microcavity quality factors Q. Here, we examine what confinement and Q can be reached in these hybrid systems, and we address their merits for various applications in classical and quantum optics.
