摘要：
The phase dynamics of a closed 0-pi junction is investigated. Such a system can be realized, for example, in a small d(x(2)-y(2))-wave superconductor embedded in a conventional s-wave superconducting matrix. The Hamiltonian of the system is derived. We prove that the system can be mapped on a quantum two-level system when the system size is small enough.
