Award Description: Mesoscopic superconductors are defined by a characteristic size comparable with the zerotemperature superconducting coherence length, which often fall into submicron or nanometer regimes. In recent years there has been intensive scientific and technological interest on these new superconducting systems. While great advances have been made in this area of research, fundamental questions remain to be addressed. We propose to form a Materials World Network (MWN) team consisting five experimentalists and two theorists from China, Colombia, Japan, Switzerland, and the US to investigate unusual, mostly unexplored mesoscopic superconductors.
Project Description: Project will focus on addressing several fundamental issues on mesoscopic superconductors, will lead to new discoveries and deeper understanding of superconductivity and mesoscopic physics. By varying the sample topology and shrinking the sample size, which has never done previously, we expect that our work will uncover many novel physical phenomena. By making use of the recently available unconventional mesoscopic superconductors, we will push our understanding of unconventional mesoscopic superconductivity to a new level. Finally, by investigating p-wave S/F/S Josephson junctions, for which dramatic phenomena have been predicted theoretically, we expect to obtain new insights into Josephson effects in unconventional superconductors.Specifically we will: 1) study ultrasmall mesoscopic superconductors that feature a doubly or multiply connected sample geometry as well as a destructive regime; 2) investigate mesoscopic, conventional s-wave superconductor, or a normal metal bordered by an unconventional, chiral pwave superconductor; 3) explore p-wave superconductor-ferromagnetic metal-superconductor (S/F/S) Josephson junctions and strive to understand the subtle interplay between exchange and pairing interactions; and 4) to pursue integrated research and education activities.
