Definition: In physics and quantum mechanics, a coindwelling state is a state where two or more particles are simultaneously in motion. This phenomenon occurs when two or more particles are bound together, but they are not interacting with each other directly. Instead, the two particles are coupled through some mechanism that allows them to exchange energy without actually moving apart. For example, consider a system of particles that are bound together by electromagnetic forces. If one particle is allowed to move away from the other, this will create
