Influence of Microwave Radiation on Current‐Voltage Characteristic of Superconducting Weak Links
TLDR
In this paper, the currentvoltage characteristics of microwave-irradiated superconducting weak links have been calculated on the analog computer and the results of several authors can be interpreted correctly by taking into consideration the resistive feedback.Abstract:

TL;DR: The observation of an anomalous response to rf irradiation in a Josephson junction made of a HgTe weak link is reported, understood as due to a 4π-periodic contribution to the supercurrent, and its amplitude is compatible with the expected contribution of a gapless Andreev doublet.

Dissipative dynamics of the Frenkel-Kontorova model
Luis Mario Floría,Juan J. Mazo +1 more
TL;DR: In this article, the authors present recent advances in the theory of the dynamics of modulated phases in the Frenkel-Kontorova model, motivated through two specific condensed matter systems: charge-density wave conductors and Josephson junction arrays.

The ac Josephson effect in hysteretic junctions: Range and stability of phase lock
TL;DR: In this article, the effect of noise on phase lock was investigated in the context of the Stewart-McCumber model and the results were applied to a zero bias voltage standard proposed by Levinsen et al.
Book ChapterDOI
The two-dimensional physics of Josephson junction arrays
TL;DR: In this paper, the authors discuss the two-dimensional physics of Josephson junction arrays, which consist of islands of superconductor, usually arranged on an ordered lattice, coupled by Josephson junctions.

Effect of ac Impedance on dc Voltage‐Current Characteristics of Superconductor Weak‐Link Junctions
TL;DR: In this paper, the effect of the Josephson pair current in a weak-link superconductor junction is considered and two special cases which illustrate the basic principles involved are worked out.
Journal ArticleDOI
Current‐voltage characteristics of josephson junctions
TL;DR: In this paper, a model for superconducting Josephson junctions analogous to the driven simple pendulum with damping gives dc I•V curves displaying hysteresis for light damping.
Journal ArticleDOI
Supercurrents through barriers
TL;DR: In this paper, a phenomenological theory was developed and applied to a number of topics, such as penetration of a magnetic field into a barrier, interference of supercurrents in the presence of magnetic field, the cut-off frequency associated with the propagation of electromagnetic waves along a barrier and structure in the d.c. supercurrent.

Behavior of thin-film superconducting bridges in a microwave field.
A.H. Dayem,J.J. Wiegand +1 more
TL;DR: In this article, the behavior of thin-film superconducting bridges in the presence of an applied microwave field was investigated and it was found that the critical current with the field is more pronounced at higher frequencies and at temperatures closer to the transition temperature.
