摘要

We predict "heating" of quasiparticles driven by order parameter oscillations in the resistive state of short superconducting microbridges. The finite relaxation time of the magnitude of the order parameter | A| and the dependence of the spectral functions both on | A | and the supervelocity Q are the origin of this effect. Our results are opposite to those of Aslamazov and Larkin [Zh. Eks. Teor. Fiz. 70, 1340 (1976)1 and Schmid et al. [Phys. Rev. B 21 5076 (1980)] where "cooling" of quasiparticles was found.
