Plasma effects on lifetimes and screening of Rydberg excitons
AbdAlGhaffar Amer, V. Walther, Francis Robicheaux
We simulate the effects of a neutral electron--hole plasma on Rydberg excitons in cuprous oxide (CuO), focusing on the validity of Debye screening and the role of plasma-induce…
Photon statistics in waveguide QED: II Exact solutions in a thermodynamic limit
M. Eltohfa, F. Robicheaux
Waveguide quantum electrodynamics (WQED) offers a powerful framework for controlling light-matter interactions and realizing collective phenomena such as super- and subradiance. In…
Photon statistics in chiral waveguide QED: I Mean field and perturbative expansions
M. Eltohfa, F. Robicheaux
Waveguide Quantum Electrodynamics (WQED) offers a suitable stage for controlling the interaction of light with atoms, allowing for collective phenomena such as super- and subradian…
High-resolution spectroscopy of 162Dy Rydberg levels
G. Ferioli, P. Lombardi, P. Sekhar +9
Highly excited Rydberg states of lanthanides are a promising, yet largely unexplored, playground for quantum studies. Here, we report on the first high-resolution spectroscopy of 1…
Collective emission and selective radiance in atomic clouds and arrays coupled to a microring resonator
Deepak A. Suresh, Xinchao Zhou, Chen-Lung Hung +1
We theoretically investigate the collective dipole-dipole interactions in atoms coupled to a nanophotonic microring resonator. The atoms can interact with each other through light-…
Emission photon statistics in collectively interacting dipole atom arrays in the low-intensity limit
Deepak A. Suresh, F. Robicheaux
We investigate the photon statistics of light emitted from a system of collectively interacting dipoles in the low-intensity regime, incorporating double-excitation states to captu…
Selective collective emission from a dense atomic ensemble coupled to a nanophotonic resonator
Xinchao Zhou, Deepak A. Suresh, F. Robicheaux +1
We experimentally and theoretically study collective emission of a dense atomic ensemble coupled to a single mode in a nanophotonic microring resonator. Because many cold atoms are…
Effects of finite trapping on the decay, recoil, and decoherence of dark states of quantum emitter arrays
M. Eltohfa, F. Robicheaux
The collective interaction of electronic excitations with the electromagnetic field in atomic arrays can lead to reduced decay rates, forming subradiant states with applications in…
