Superconductivity in curved 3D nanoarchitectures — •Vladimir M. Fomin^1,2 and Oleksandr V. Dobrovolskiy³ — ¹Institute for Integrative Nanosciences (IIN), Leibniz IFW Dresden, D-01069 Dresden, Germany — ²Laboratory of Physics and Engineering of Nanomaterials, Department of Theoretical Physics, Moldova State University, MD-2009 Chişinău, Republic of Moldova — ³University of Vienna, Faculty of Physics, Nanomagnetism and Magnonics, Superconductivity and Spintronics Laboratory, 1090 Vienna, Austria

In recent years, superconductivity and vortex matter in curved 3D nanoarchitectures have turned into a vibrant research avenue because of the rich physics of the emerging geometry- and topology-induced phenomena and their prospects for applications in (electro)magnetic field sensing and information technology. We outline the experimental techniques capable of the fabrication of curved 3D nanostructures and present a selection of own results on the intertwined dynamics of screening superconducting currents, Abrikosov vortices and slips of the phase of the superconducting order parameter therein. We share our vision regarding the prospect directions and current challenges in this research domain, arguing that curved 3D nanoarchitectures open a new dimension in superconductors research and possess great potential for magnetic field sensing, bolometry, and fluxonic devices [1].
