Abstract
AbstractThe quasiparticle charge imbalance relaxation time in the nonequilibrium state of a phase slip centre in indium whiskers is calculated taking into account the depairing effect due to supercurrent and the finite size of the core. The normal‐like length for the first phase slip centre for various temperatures below the transition temperature is calculated and compared with the experimental data. The analysis shows that the core of phase slip centre is about four times the Ginzburg‐Landau coherence length. This result is new. Further the effect of pair breaking due to supercurrent on the charge imbalance relaxation time for various values of τE is calculated for temperatures 1 to 50 mK away from the transition temperature.
