Quasi-particles are collective quantum elements of condensed matter. They are foundationally important for understanding ...

Each electron carries one unit of negative charge (1.602 x 10-19 coulomb) and has a mass of just about 1/1836th of a proton. Electrons are found both not permanently attached to atoms and within ...

If an object loses electrons it has a positive charge. We can calculate the electrostatic force between two charged objects with Coulomb’s law. This says that the force between them depends on ...

In a paper published Jan. 22 in Nature, the team describes how electrons in devices made, in part, of the new material can become solid, or form crystals, by changing the voltage applied to the ...

This allows the electrons to move like a free-flowing gas. If you remove an electron from a metal and insert it back in, electrostatic forces (Coulomb force) will move the neighboring electron ...

We are at a critical time and supporting climate journalism is more important than ever. Science News and our parent organization, the Society for Science, need your help to strengthen ...
