Influence of temperature on the resonant behavior.
The resonant behavior in V(τ) for different bath temperatures (a), and for varied maximal temperature in the channel (b). (a) With increasing the bath temperature, a transition to a higher dissipative state may occur, where additional vortices move outside of the channel, thus creating additional harmonics that will smear out the average voltage from the 1/τ behavior [depicted by Cooper-pair density snapshots (1) for observable resonances and (2) for smeared resonances]. (b) By varying the maximal temperature in the channel, one may selectively switch between different vortex phases, from Abrikosov vortex, transitional state between Abrikosov and Josephson vortex, and to Josephson vortex [depicted by Cooper-pair density snapshots (1)–(3), respectively, at τ = 1000τGL(0)]. The animations of different vortex species during one period of the characteristic dynamics of the condensate are provided in the Supplementary Materials (entitled Supplementary-Animation2.gif).
