摘要: Small capacitance tunnel junctions show single electron effects and, in the superconducting state, coherent tunneling of Cooper pairs. We study these a system two Josephson junctions, driven by voltage source with finite impedance. Novel features up theI−V characteristics, particular pronounced structures at subgap voltages. These are due to pair tunneling, combined quasiparticles or excitation electromagnetic environment.
