Physicists have achieved a phenomenon known as subradiance, in which atoms linger in an excited state, in a dense cloud of atoms...
Atoms gain energy by absorbing photons (light particles) that cause their electrons to jump from the lowest-energy "ground" state to higher-energy excited states. Once they're in an excited state, atoms spontaneously emit a photon and fall back to the ground state. But this isn't always the case. If many atoms are packed together and separated by a shorter distance than the wavelength of the emitted photon, the light they emit will cancel itself out, and the atoms will stay in their excited state.
This process, called subradiance, effectively staves off the decay of a large group, or "ensemble," of excited atoms. Subradiance has been observed before in dilute atomic ensembles and ordered atomic arrays, but never before in dense atomic clouds.
Subradiance works because of a phenomenon called destructive interference. When two waves of light with the same amplitude are made to occupy the same part of space, the peaks and the troughs of the waves can align to add together constructively, making a combined wave that is twice as bright, or destructively, cancelling out both waves entirely.
On the tiny scale of the weird quantum world, particles both have wave-like properties and can simultaneously travel all the infinite paths between one point and another. The path the particle "chooses" to take, and the one we observe, depends on how the wave-like particles interfere with themselves. It's not really the destructive interference between any emitted photons that traps atoms in excited states, but instead — and here's the wacky part — the possibility that it might happen, which stops the photons from being emitted in the first place.

Power plant workers can now take home electricity sneaked away in their lunch bucket.
LOL..One of these days the “Science Fair” crowd will turn off the lights for good...
Extremely yawnable...

Phenomena on the border line between causality and synchronicity.
Interesting.
The more we study, the more we learn what we don’t know.
Everytime I read these kinds of physics-based papers it reinforces my faith in God the Creator.
Unfortunately, after seeing proof time and time again Science continues to disbelieve in God even after knowing that the universe is Intelligently designed.
That is an interesting way of putting it.
Thats where her power comes from. She is an en-trapper. She sure set off Lindsey Graham in the Kavanaugh confirmation hearings.
I;d say she is just about the most hateful politcian in Washington except for Nancy Pelosi.
WHAT????
“Once they’re in an excited state, atoms spontaneously emit a photon and fall back to the ground state.”
Most guys are like that.
