FIG. 1.

An SNS junction between two superconducting electrodes (reservoirs in blue on the right and left), formed by a metallic carbon nanotube with a fullerene molecule impurity which can move freely inside the tube. The mobile “impurity” is attracted to the superconductor leads for equilibrium populations of the Andreev bound states, and can levitate inside the tube for nonequilibrium level occupations.

FIG. 2.

The force (in units of F 0 =  v F RL 2) as a function of normalized temperature T/T* for ϕ = 0 (smooth curve), 2 (dotted), and 3.14 (dashed). l/L = 0.7.

FIG. 3.

The force (in units of F 0 =  v F RL 2) as a function of the normalized coordinate l/L for two different values of phase difference: ϕ = π/12 (smooth) and ϕ = π (dashed).

Image of FIG. 4.
FIG. 4.

The phase-dependent part of the force, ΔF(ϕ) = F(ϕ) − F(0) (in units of F 0 =  v F RL 2) for two different temperatures, T = 0 (smooth) and T/T * = 3 (dashed).
