and where vc is the cyclotron frequency. The exact spectrum of the interacting electron system therefore contains an infinite ladder of energy levels at integer multiples of 2\V . However, these authors do not explain why the unphysical 1/r interaction is special, apart from the mathematical fact that it permits a separation of the many-particle Schrödinger equation in the hyperradial and hyper...
