Researchers have simplified a highly complex quantum imaging technique, 2DES, used to observe ultrafast electron interactions. By refining an existing interferometer design, they improved control over ...

If an electron is in an excited state it can return to a lower energy level. When it does this, it loses energy. The amount of energy it loses will be equal to the difference in the energy levels ...

The excitation of a material with high-energy photons can produce what is known as an electron-hole plasma. This state is characterized by the dense presence of negatively charged particles (i.e ...
