Ignition of superconducting vortices by acoustic standing waves

Jaroslav Albert, E. M. Chudnovsky

英文摘要:

Nucleation of vortices in a superconductor below the first critical field can be assisted by transverse sound in the GHz frequency range. Vortices will enter and exist the superconductor at the frequency of the sound. We compute the threshold parameters of the sound and show that this effect is within experimental reach.
