Abstract:We have used a dc SQUID (Superconducting Quantum Interference Device) to study vortex-antivortex pair creation in both two-dimensional superconducting films and Josephson junction arrays in the presence of 850 nm light irradiation. Specifically the experiments aim to distinguish between the formation of vortex-antivortex pairs by single photon absorption and by thermal activation. The major objective for this experiment is to investigate the possibility of photon-induced vortex-antivortex pair creation.
