👉 In the context of quantum mechanics, a "preconcentration" is a phenomenon where particles (such as electrons or photons) are separated from each other and become more densely packed together. This can be described as an increase in the volume of the particle being concentrated around it. The term "preconcentrating" is often used to describe phenomena that result from the interaction between two or more particles, such as electrons interacting with a magnetic field or photons interacting with a medium. In this context,
