“…The reason, that the position of the breakpoints are shifted from the boundary of the resonance region in Fig. 4a, is the linear approximation used to obtain the equation (9). The breakpoints are inside of the resonance region, i.e.…”

“…A unified theory for magnetic and electric coupling in multistacked Josephson junctions was developed. 8 The capacitively coupled Josephson junction model (CCJJ) seizes the main dynamical properties of the IJJ system, describes the multibranch structure in the IVC of the stack of IJJ 6,9 and explains the microwave resonant absorption. 10 On the other side a diffusion current plays an important role in the stack of IJJ 11 .…”

We study the breakpoint region on the outermost branch of current-voltage characteristics of the stacks with different number of intrinsic Josephson junctions. We show that at periodic boundary conditions the breakpoint region is absent for stacks with even number of junctions. For stacks with odd number of junctions and for stacks with nonperiodic boundary conditions the breakpoint current is increased with number of junctions and saturated at the value corresponding to the periodic boundary conditions. The region of saturation and the saturated value depend on the coupling between junctions. We explain the results by the parametric resonance at the breakpoint and excitation of the longitudinal plasma wave by Josephson oscillations. A way for the diagnostics of the junctions in the stack is proposed.

“…The effect of collective excitations on radiation power from the stack is not studied in detail yet. In this paper, we investigate the IV-curve of stacked JJs and radiation power from the stack taking into account the inductive and capacitive couplings [14,15] and the diffusion current [5,16,17].…”

Abstract. 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.

“…Machida and Sakai [13] proposed a generalization of the model to the case of both inductive and capacitive coupling. However, they disregarded the diffusion current [14], the significance of which was emphasized in [15]. Furthermore, the CVC have not yet been studied within the generalized Machida-Sakai model.…”

Abstract. The phase dynamics of the stacked long Josephson junctions is investigated taking into account the inductive and capacitive couplings between junctions and the diffusion current. The simulation of the current-voltage characteristics is based on the numerical solution of a system of nonlinear partial differential equations by a fourth order Runge-Kutta method and finite-difference approximation. A parallel implementation is based on the MPI technique. The effectiveness of the MPI/C++ code is confirmed by calculations on the multi-processor cluster CICC (LIT JINR, Dubna). We demonstrate the appearance of the charge traveling wave (CTW) at the boundary of the zero field step. Based on this fact, we conclude that the CTW and the fluxons coexist.
