Parametrically pumped superconducting circuits

by Philip Krantz, Philip Krantz, Philip Krantz, Philip Krantz , 2013
"... In this licentiate thesis, I present the design, fabrication, and character-ization of superconducting parametric resonators, for use in quantum information processing. These devices are quarter-wavelength coplanar waveguide resonators ( ≈ 5 GHz), terminated at one end by a non-linear inductance pro ..."

Parametric resonance in superconducting micron-scale waveguides

by N V Fomin , ) O L Shalaev , D V Shantsev , A F - J. Appl. Phys , 1997
"... A parametric resonance due to temperature oscillations in superconducting micron-scale waveguides is considered. Oscillations of superconductor temperature are assumed to be induced by the irradiation of the waveguide with a laser beam. The laser power and parameters of the waveguide providing a po ..."

Stimulated superconductivity at strong coupling

by Ning Bao, Xi Dong, Eva Silverstein, Gonzalo Torroba
"... Stimulating a system with time dependent sources can enhance instabilities, thus increasing the critical temperature at which the system transitions to interesting lowtemperature phases such as superconductivity or superfluidity. After reviewing this phenomenon in non-equilibrium BCS theory (and its ..."

A Wideband, Low-Noise Superconducting Amplifier with High Dynamic Range

by unknown authors
"... Amplifiers are ubiquitous in electronics and play a fundamental role in a wide range of scientific measurements. From a user’s perspective, an ideal ampli-fier has very low noise, operates over a broad frequency range, and has a high dynamic range- it is capable of handling strong signals with littl ..."

the quantum-mechanical limit.[2] Indeed, microwave frequency superconducting Josephson parametric amplifiers[3, 4] do approach the quantum limit, but generally are narrow band and have very limited dynamic range. In this paper, we describe a superconducting parametric amplifier that overcomes

COLOR SUPERCONDUCTIVITY IN COLD, DENSE QUARK

by D. H. Rischke, R. D. Pisarski , 2000
"... We review what is different and what is similar in a color superconductor as compared to an ordinary BCS superconductor. The parametric dependence of the zero-temperature gap, φ0, on the coupling constant differs in QCD from that in BCS theory. On the other hand, the transition temperature to the su ..."

PARAMETRIC GRAVITY WAVE DETECTOR

by G. Gemme, A. Chincarini, R. Parodi, Ph. Bernard, E. Picasso , 2001
"... Since 1978 superconducting coupled cavities have been proposed as a sensitive detector of gravitational waves. The interaction of the gravitational wave with the cavity walls, and the resulting motion, induces the transition of some energy from an initially excited cavity mode to an empty one. The e ..."

Stimulating uncertainty: Amplifying the quantum vacuum with superconducting circuits

by P. D. Nation, J. R. Johansson, M. P. Blencowe, Franco Nori , 2012
"... The ability to generate particles from the quantum vacuum is one of the most profound consequences of Heisenberg’s uncertainty principle. Although the significance of vacuum fluctuations can be seen throughout physics, the experimental realization of vacuum amplification effects has until now been l ..."
