| Popis: | We consider the dynamical behaviour of systems composed of multiple Josephson junctions, both theoretically and experimentally, using the examples of three-junction and four-junction interferometers. Numerical simulations and stability considerations based on the Lyapunov method show that only one fundamental phase state of the interferometer is allowed. The experimental investigation of four-junction interferometers also shows no evidence of the existence of higher interferometer states. |
