Does the persistent current in a quantum loop depend on an electron-electron interaction?
Govorov A. O., Chaplik A. V., Wendler L., Fomin V. M.
The mechanism for the "exclusion" of the Coulomb interaction from the expression for the persistent current is clarified in the limit of a strong correlation of the electrons forming a Wigner molecule in a ID loop. The cases in which theories with and without the interaction lead to different results are identified. ©
