Special Issue Information

Dear Colleagues,

Big data analysis requires computations to have high energy efficiency and can benefit from the adoption of new computing paradigms. Recent research has found superconducting electronics to be a promising technological platform in this respect, with potential applications in many fields such as quantum chemistry and materials science, artificial intelligence, cryptography, media processing, and optimization tasks. Macroscopic quantum effects associated with the superconducting state of a material also form the basis of various highly sensitive sensors and systems for signal receiving and processing. This Special Issue aims to cover the latest discoveries in the innovating modern electronics of superconducting systems. We welcome full articles, communications, and reviews devoted to the theory and simulation of superconducting nanomaterials and nanostructures, theoretical and experimental studies on their basic properties, synthesis and fabrication routes, device methods, and other topics that bridge the gap between fundamental physics of superconductivity and device engineering. The research directions highlighted in this Special Issue include, but are not limited to, the following:

  1. Superconducting/ferromagnetic nanoscaled spin valves;
  2. Hybrid superconducting nanostructures with electrically tunable critical currents;
  3. The controllable kinetic inductance of superconducting nanostructures;
  4. Superconducting nanostructures for sensors and receiving systems;
  5. Superconducting switching devices for digital electronics;
  6. Nanomaterials and nanoscaled systems of superconducting quantum electronics;
  7. Neuromorphic applications of superconducting nanostructures;
  8. The theory and simulation of superconducting phenomena on nanoscales for emerging applications.

We have studied the proximity effect in an SF1S1F2s superconducting spin valve consisting of a massive superconducting electrode (S) and a multilayer structure formed by thin ferromagnetic (F1,2) and superconducting (S1, s) layers. Within the framework of the Usadel equations, we have shown that changing the mutual orientation of the magnetization vectors of the F1,2 layers from parallel to antiparallel serves to trigger superconductivity in the outer thin s-film. We studied the changes in the pair potential in the outer s-film and found the regions of parameters with a significant spin-valve effect. The strongest effect occurs in the region of parameters where the pair-potential sign is changed in the parallel state. This feature reveals new ways to design devices with highly tunable inductance and critical current. Full article

It is known that the dielectric layer (resonator) located behind the conducting plate of the bolometer system can significantly increase its sensitivity near the resonance frequencies. In this paper, the possibility of receiving broadband electromagnetic signals in a multilayer bolometric meta-material made of alternating conducting (e.g., silicon semiconductor) and dielectric layers is demonstrated both experimentally and numerically. It is shown that such a multilayer structure acts as a lattice of resonators and can significantly increase the width of the frequency band of efficient electromagnetic energy absorption. The parameters of the dielectric and semiconductor layers determine the frequency bands. Numerical modeling of the effect has been carried out under the conditions of our experiment. The numerical results show acceptable qualitative agreement with the experimental data. This study develops the previously proposed technique of resonant absorption of electromagnetic signals in bolometric structures. Full article
