what is the einsteinbrillouinkeller quantization condition?
user
the einstein–brillouin–keller (ebk) quantization condition is a quantum-mechanical rule that specifies the allowed energy levels or “quantum states” of a particle confined in a particular region of space. it states that when the particle has a total energy that is the sum of some multiple of the energy of the particle's motion in the region, it is allowed to exist in a distinct quantum state. the particle's motion is restricted to a certain area of space and its energy must be an integer number of times its angular momentum. this quantization condition is named after the three physicists who developed it: albert einstein, léon brillouin, and jacobus kapteyn.
