Topological and Chiral Superconductor Nanoarchitectures

3D nano-superconductors, with non-trivial geometry-driven topological phenomena, stand as promising systems for the future evolution of efficient and multifunctional technologies. However, the substantial challenges inherent in the experimental work, particularly regarding the fabrication and characterization of 3D nanoscale geometries and unconventional topologies of superconducting states, have confined the majority of investigations in this domain until recently to the realms of computational and theoretical studies. We overview the recent advancements in fabricating superconductor 3D nanoarchitectures and unveiling their fascinating physical properties that occur due to the geometry-induced topology and chirality, which offer a broad spectrum of applications of these nanostructures for the front-line development of various modern technologies.
