Producing Mechanism of Microwave-induced Steps observed in BSCCO Intrinsic Josephson Junctions

Shapiro Steps in BSCCO Intrinsic Josephson Junctions

Microwave-induced thermal escape in Josephson junctions.

We investigate, by experiments and numerical simulations, thermal activation processes of Josephson tunnel junctions in the presence of microwave radiation. When the applied signal resonates with the Josephson plasma frequency oscillations, the switching current may become multivalued in a temperature range far exceeding the classical to quantum crossover temperature. Plots of the switching cur...

Shapiro steps in Josephson Junctions

We use Ginzburg-Landau theory to describe the phase transition to the superconducting state and the current through a superconductor. Applying quantum mechanics to the Josephson junction following Feynmann’s method the Josephson relations for AC and DC current through the junctions is obtained. The resistively shunted Josephson junction and the resistively and capacitively shunted Josephson jun...

Static Charge Coupling of Intrinsic Josephson Junctions

Since the discovery of the intrinsic Josephson effect not only the typical properties of conventional junctions were demonstrated [1], but also unique and surprising features like the coupling of Josephson oscillations to phonons [2] have been discovered. There has also been a considerable interest in the influence of nonequilibrium effects on the I − V -characteristic and collective modes [3– ...

Dynamical Behaviour of Intrinsic Josephson Junctions

Intrinsic Josephson Junctions (IJJs) are the subject of much of research due to their potential applications as high frequency oscillators and detectors in the THz range. A number of previous studies use a single junction model to explain their observations, as no fully agreed model for coupled IJJs exists. The influence of one or more IJJs in the voltage state on other junctions in the IJJ arr...
