{wiki=Particle_in_a_ring}
A "particle in a ring" is a fundamental problem in quantum mechanics that describes a quantum particle constrained to move on the circumference of a circle (or ring) of a fixed radius. This model is significant for understanding certain concepts in quantum mechanics, such as quantization, angular momentum, and the behavior of particles in systems with circular symmetry.
