Advances in the high-tech fabrication methods have provided novel curved micro- and nanoarchitectures of superconductors, e.g., nanostructured microtubes, helical microcoils and their arrays.
Atoms and photons interact in free space in one of nature’s most fundamental processes. The dipolar interaction strength between the two systems is determined by fundamental constants, with one of its limiting factors being the mode volume of the propagating photons.
Superconductivity induced by proximity effect is particularly interesting in graphene.
The narrow-band semiconductor PbTe superconducts with a Tc an order of magnitude greater than comparable low-density metals, but only when it is doped with valence-skipping elements.
The superconductor-insulator transition (SIT) is a quantum phase transition in disordered superconducting films that occurs at the point where two inherently two-dimensional topological phase transitions - charage and vortex Berezinskii-Kosterlitz-Thouless (BKT) transitions - terminate each other.
