TL;DR: Observations close to critical disorder provide strong evidence that phase fluctuations play a central role in the formation of a pseudogap state in a disordered s-wave superconductor.

TL;DR: In this paper, the authors measured the magnetotransport properties and Hall effect of a series of epitaxial NbN films grown on (100) oriented single crystalline MgO substrate under different conditions using reactive magnetron sputtering.

TL;DR: The Higgs mechanism is best known for generating mass for subatomic particles as mentioned in this paper, but the idea originated in the study of superconductivity, and can be tested in the laboratory.

TL;DR: In this paper, an impedance engineered Josephson parametric amplifier capable of providing bandwidth beyond the traditional gain-bandwidth product was proposed, by introducing a positive linear slope in the imaginary component of the input impedance seen by the Josephson oscillator using a λ/2 transformer.

TL;DR: In this article, an impedance engineered Josephson parametric amplifier capable of providing bandwidth beyond the traditional gain-bandwidth product is presented, which is achieved by introducing a positive linear slope in the imaginary component of the input impedance seen by the Josephson oscillator using a $\lambda/2$ transformer.
