“…For the currents greater then the critical the Josephson junction is in the restive state characterized by the finite voltage value on the IV characteristics, absence of charging on the superconducting electrodes and high intensity THz radiation emission. 2 In the arrays of Josephson junctions composed by alternating superconducting and insulating (normal metal) layers novel phenomena appear. An array of Josephson junctions can be described using two dimensionless parameters: dissipation defined by the sample temperature and the materials used for the array fabrication, and the coupling parameter defined by the thickness of the insulating layers and the materials used for the array fabrication.…”

Strongly coupled, highly dissipative arrays of Josephson junctions are characterized by presence of two branches for the currents greater then the critical one in their IV characteristic. Additional branch, called traveling wave branch is characterized by low voltage, generation of charge density waves in the stack. Traveling wave branch appears on the IV characteristic only if coupling and dissipation parameters have the values above their thresholds. In this work we focused on the study of charge density waves behavior in the specified type of Josephson junction arrays in order to explain the stability of the traveling wave branch. Were performed numerical simulations using Capacity Coupled Josephson Junctions with Diffusion Current (CCJJ+DC) model which gives good agreement with the experimental results and were obtained IV-characteristics and charge density temporal evolution profiles for different currents corresponding to traveling wave branch. Was shown that the form of charge density waves changes with the increase of current. Moreover was studied spectral structure of charge density waves and dependence of Lissajous correlations between charge accumulated on the neighbor superconducting layers on the current. thought the stack.

“…Though the RCLSJJO was not considered extensively regarding the literature of the JJ, its vast uses and technological integration have subjected the circuit design to increasing research findings. The existing literature on the model and application has been exposed recently by different scholars [21,26,[29][30][31][32][33][34][35], but PRNG and combination synchronization in the model at low critical temperature superconductor is not investigated and remains open. This aspect is interesting as it observed security in communications which is investigated in this research paper.…”

Dynamical scrutiny of the resistive capacitive inductive shunted Josephson junction (JJ) oscillator (RCLSJJO), microcontroller realization, pseudo-random number generation (PRNG) and combination synchronization are achieved in this paper. Numerical probing led to the establishment that the RCLSJJO is characterized by regular behaviors, bistable periodic-2-oscillations, periodic bursting characteristics and various shapes of chaotic dynamics. Thereafter, the vast dynamical characteristics obtained theoretically are realized by the microcontroller realization with qualitative agreements. Moreover, a chaos-based PRNG is designed by using chaotic RCLSJJO and linear feedback shift register (LFSR) as post-processing unit. Satisfactory results are obtained from the NIST 800–22 test suite and the randomness of binary data generated from the proposed RCLSJJO-based PRNG is confirmed for chaos-based digital applications. Lastly, the combination chaos synchronization of two drive and one response RCLSJJO is proven thanks to the theoretical analysis.
