Light in correlated disordered media
The optics of correlated disordered media is a conceptually rich research topic emerging at
the interface between the physics of waves in complex media and nanophotonics. Inspired …

Subradiance in a large cloud of cold atoms
Since Dicke's seminal paper on coherence in spontaneous radiation by atomic ensembles,
superradiance has been extensively studied. Subradiance, on the contrary, has remained …

Non-Hermitian Rosenzweig-Porter random-matrix ensemble: Obstruction to the fractal phase
We study the stability of nonergodic but extended (NEE) phases in non-Hermitian systems.
For this purpose, we generalize the so-called Rosenzweig-Porter random-matrix ensemble …

Pseudogap and Anderson localization of light in correlated disordered media
Among the remarkable scattering properties of correlated disordered materials, the origin of
pseudogaps and the formation of localized states are some of the most puzzling features …

Localization of scattering resonances in aperiodic Vogel spirals
By using the dyadic Green's matrix spectral method, we demonstrate that aperiodic
deterministic Vogel spirals made of electric dipoles support a light localization transition in …

Imaginary gap-closed points and dynamics in a class of dissipative systems
S Ma, H Lin, J Pi - Physical Review B, 2024 - APS
We investigate imaginary gap-closed (IGC) points and their associated dynamics in
dissipative systems. In a general non-Hermitian model, we derive the equation governing …

Population of collective modes in light scattering by many atoms
W Guerin, R Kaiser - Physical Review A, 2017 - APS
The interaction of light with an atomic sample containing a large number of particles gives
rise to many collective (or cooperative) effects, such as multiple scattering, superradiance …

Photon-mediated dipole-dipole interactions as a resource for quantum science and technology in cold atoms
HH Jen - arxiv preprint arxiv:2410.20665, 2024 - arxiv.org
Photon-mediated dipole-dipole interactions arise from atom-light interactions, which are
universal and prevalent in a wide range of open quantum systems. This pairwise and long …

Aperiodicity is more effective than disorder in localizing electromagnetic waves
Strong localization of electromagnetic waves in 3D has never been experimentally achieved
in uncorrelated disordered systems. By going beyond the paradigm of disordered systems …
