Macroscopic Quantum Tunneling in a Josephson Junction Coupled
... If we think of the JJ as a mass on a spring then perhaps it makes sense that increasing the coupling strength between it and another oscillator decreases its amplitude, since this means that the coupling spring gets stiffer. This effect is even more evident when the resonator frequency is small, sin ...
