Transient dynamics of a superconducting nonlinear oscillator
P. Bhupathi, Peter Groszkowski, M. P. DeFeo +3
We investigate the transient dynamics of a lumped-element oscillator based on a dc superconducting quantum interference device (SQUID). The SQUID is shunted with a capacitor formin…

Microstrip superconducting quantum interference device amplifiers with submicron Josephson junctions: enhanced gain at gigahertz frequencies
M. P. DeFeo, P. Bhupathi, K. Yu +4
We present measurements of an amplifier based on a dc superconducting quantum interference device (SQUID) with submicron Al-AlOx-Al Josephson junctions. The small junction size red…

Ultrasound attenuation of superfluid He in aerogel
H. C. Choi, N. Masuhara, B. H. Moon +7
We have performed longitudinal ultrasound (9.5 MHz) attenuation measurements in the B-phase of superfluid He in 98% porosity aerogel down to the zero temperature limit for a wi…
