A movable Cooper-pair box shows reentrant dynamical stability with two Hopf bifurcations, whose character (subcritical vs supercritical) depends on the adiabaticity of Andreev tunneling.
The continued equilibrium branch is parameterized as ( X0(s), η(s)), where s is an auxiliary continuation parameter corresponding to the pseudo-arclength along the branch

Nonlinear nanoelectromechanics of a movable Cooper-pair box
A movable Cooper-pair box shows reentrant dynamical stability with two Hopf bifurcations, whose character (subcritical vs supercritical) depends on the adiabaticity of Andreev tunneling.
