In physics, there are very different types of particles: Elementary particles are the fundamental building blocks of matter. Other particles, such as atoms, are bound states consisting of several smaller constituents. And then there are so-called “quasi-particles”—excitations in a system that consists of many particles, which in many ways behave just like a particle themselves.
