Photon-assisted macroscopic quantum tunneling in a slightly current-biased Josephson junction with a small capacitance and a low damping factor is proposed to occur between the quantized energy levels in adjacent potential wells by photon absorption or emission. The tunneling rate is calculated by t

The Josephson effect is one manifestation of the quantum aspect of macroscopic objects. It has been tested in various macroscopic systems to confirm their quantummechanical nature. In some of the systems, the total number of particles in the system is fixed. In such a case, the dynamics of the syst
