Strongly subradiant states in planar atomic arrays [PDF]
NanophotonicsThe optically trapped ensembles of atoms provide a versatile platform for storing and coherent manipulation of quantum information. However, efficient realization of quantum information processing requires long-lived quantum states protected from the ...

Multidimensional super- and subradiance in waveguide quantum electrodynamics
Physical Review Research, 2020 We study the collective decay rates of multidimensional quantum networks in which one-dimensional waveguides form an intersecting hyperrectangular lattice, with qubits located at the lattice points.

Directional spontaneous emission in photonic crystal slabs [PDF]
NanophotonicsSpontaneous emission is one of the most fundamental out-of-equilibrium processes in which an excited quantum emitter relaxes to the ground state due to quantum fluctuations.

Collective single-photon emission and energy transfer in thin-layer dielectric and plasmonic systems [PDF]
NanophotonicsWe study the collective photon decay of multiple quantum emitters embedded in a thin high-index dielectric layer such as hexagonal boron nitride (hBN), with and without a metal substrate.

Cavity-mediated collective emission from steady-state subradiance [PDF]
Nature CommunicationsCooperative effects such as super(or sub)radiance in quantum systems arise from the interplay among quantum emitters. While bright superradiant states have been extensively studied and have yielded important insights into cooperative phenomena ...

Optimization of photon storage fidelity in ordered atomic arrays [PDF]
New Journal of Physics, 2018 A major application for atomic ensembles consists of a quantum memory for light, in which an optical state can be reversibly converted to a collective atomic excitation on demand. There exists a well-known fundamental bound on the storage error, when the

Directional subradiance from helical-phase-imprinted multiphoton states [PDF]
Scientific Reports, 2018 We theoretically investigate the far-field scattering properties of multiphoton super- and subradiant states which can be prepared by multiphoton excitations with orbital angular momentum (OAM).

Negative refraction of light in an atomic medium [PDF]
Nature CommunicationsThe quest to manipulate light propagation in ways not possible with natural media has driven the development of artificially structured metamaterials. One of the most striking effects is negative refraction, where the light beam deflects away from the ...

Controlling narrowband phosphorescence and delayed fluorescence by aggregate size [PDF]
Nature CommunicationsExciton coherence is a phenomenon involving collective electronic transition dipole moments of molecular aggregates with interesting photophysical behaviors such as superradiance and subradiance in J- and H-type aggregates, respectively. Although singlet
