The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When ...

When this happens, the column’s quantum state would undergo a transition that can be detected by a quantum sensor. “We’re playing the same game as photoelectric effect, except instead of photons – ...

The photoelectric effect, first explained by Albert Einstein in 1905, laid the foundation for quantum mechanics. It occurs when high-energy light strikes atoms, releasing electrons.

Why are these results so interesting? “The photoelectric effect was explained over a century ago by Einstein, laying the foundations for the development of quantum mechanics.

Gravity, a crucial piece of the universe, is missing from the quantum Lego set. But while there is still no quantum theory of gravity, the challenge of detecting its signatures now looks a little more ...

Max Planck really got the ball rolling for quantum physics by introducing the idea of energy coming in tiny packets, or ...

Also defying explanation was the photoelectric effect — the observation that ultraviolet light shining on a metal knocked electrons out of the metal.

The takeaway from Helgoland 2025 was that the foundations of quantum mechanics, though strongly built on Helgoland 100 years ...

The photoelectric effect, first explained in 1905, transformed our understanding of how light interacts with matter. When high-energy light hits atoms, it knocks electrons loose.
