SUMMARY:Frontiers Problems of the Josephson Effect: from macroscopic quantum phenomena to unconventional superconductivity
DESCRIPTION:I will review some general problems of superconductivity through the study of the Josephson effect, which has been in the last 50 years a continuous source of inspiration and progress in different fields. The intrinsic and robust macroscopic quantum coherence of the Josephon junctions is also the basis of well-established applications such as the superconducting quantum interference devices (SQUIDs), and of prospective hybrid architecture for quantum information.
We focus on macroscopic quantum phenomena and nanoscale effects of different types of junctions, including those employing high critical temperature superconductors (HTS). HTS oxides enlarge the occurrence of superconductivity to unexpected energy and length scales, and can be considered as representative at the same time of a wide class of materials characterized by 'exotic' superconductivity and of strongly correlated systems.
By investigating escape dynamics, we extract the quantum signature of a junction encrypted in macroscopic quantum phenomena. The moderately damped regime gives new opportunities to explore novel aspects on the interplay between coherence and dissipation, of interest for various quantum hybrid architectures. Dualism and coexistence of nano domain encoding and collective long-range order in escape dynamics of Josephson junctions and nanostructures are finally discussed. These notions should apply to all JJs and all weakly coupled Bose condensate systems.
