The core becomes so tightly packed that protons and electrons merge to form neutrons. In less than a second, the iron core, which is about the size of Earth, shrinks to a neutron core with a radius of about 6 miles (10 kilometers). The outer layers of the star fall inward on the ...

The computational method used by the quantum NOT computer is multiply realisable: it might be implemented with photons, electrons, fields, or atomic nuclei. All of these physical resources exhibit interference patterns that might be exploited to compute NOT using this computational method. But that ...
Fermions such as quarks, electrons, neutrinos, protons, and neutrons are the foundation of matter, while one category of bosons, the gauge bosons, are responsible for acting as the 'carriers' of at least three of the four fundamental forces — electromagnetism, the strong nuclear force,...
One way this happens, the researchers explain, is via the Schwinger effect—a quantum phenomenon where an electric field causes the creation of particles called electron-positron pairs (electrons and positrons have the same mass, but opposite electrical charges)....
A few photons from a stray beam of light can be enough to knock those electrons out of place and glitch a computer’s programming. Or that same optical glitching can be achieved more purposefully—say, with a very precisely targeted and well timed blast from a laser. Now that physics-...
In the context of solar cells, photons hitting a photovoltaic surface — typically a semiconductor like monocrystalline or polycrystalline silicon — impart their energy to electrons. Once the electrons gain sufficient power, they become excited and move more freely. Solar cells employ this principle ...
In the presence of light, photons dislodge a large number of electrons, which flow across the junction to create a current. This current can be used to power electrical devices, from light bulbs to cell phone chargers. Traditional solar cells use silicon in the n-type and p-type layers. ...
The aforementioned phenomenon of emitting light due to the spontaneous recombination of electrons and holes is called spontaneous emission. When the photons generated by spontaneous radiation pass through the semiconductor, once they have passed the vicinity of the emitted electron-hole pair, they can ...
