Two-level Hamiltonian of a superconducting quantum point contact
arXiv:cond-mat/9808029 · doi:10.1103/PhysRevB.59.8444
Abstract
In a superconducting quantum point contact, dynamics of the superconducting phase is coupled to the transitions between the subgap states. We compute this coupling and derive the two-level Hamiltonian of the contact.
