Effect of 2 harmonic current--phase relation on a behavior of a Josephson Traveling Wave Parametric Amplifier
Claudio Guarcello, Carlo Barone, Giovanni Carapella +3
We numerically investigate the behavior of a Josephson traveling wave parametric amplifier assuming a current-phase relation with a second--harmonic contribution. We find that vary…
Driving a Josephson Traveling Wave Parametric Amplifier into chaos: effects of a non-sinusoidal current-phase relation
Claudio Guarcello, Carlo Barone, Giovanni Carapella +4
In this work, we develop a comprehensive numerical analysis of the dynamic response of a Josephson Traveling Wave Parametric Amplifier (JTWPA) by varying the driving parameters, wi…
