A method was devised to construct a generalized dual field theory with a quantum field theory named the dual Hamiltonian (DH) method. As a simple example using this method, we examined the duality between coherent quantum phase-slip and Josephson junction (JJ) in single junction systems and nanowires. This method was proved to be reliable within the Villain approximation.

The phase dynamics of a stack of long Josephson junctions has been studied. Both inductive and capacitive couplings between Josephson junctions have been taken into account in the calculations. The IV-curve, the dependence on the bias current of the radiation power and dynamics of each JJs of the stack have been investigated. The coexistence of the charge traveling wave and fluxon states has been observed. This state can be considered as a new collective excitation in the system of coupled Josephson junctions. We demonstrate that the observed collective excitation leads to the decrease of radiation power from the system.
