Topological and geometrical effects in complex nanostructures

Organisers

Our Mini-colloquium is devoted to novel electronic, magnetic, optical and transport properties of nanostructures with complex temperature geometry and non-trivial topology emerging due to the modern advances of high-tech fabrication techniques. We intend to highlight the present state and perspectives of the key pathways in fabrication of complex 3D nanoarchitectures: roll-up self-organization and direct-writing techniques using focused electron-beam or focused ion-beam induced deposition. We expect to exchange views on diverse ongoing experimental and theoretical efforts towards understanding and engineering of their properties, which open up unprecedented potentialities for design, functionalization and integration of nanodevices. Among representative topics, we will discuss (i) how the topological transitions between vortex and phase-slips regimes in curved superconductor nanomembanes are governed by the geometry and the external stimuli (Fig. 1) and (ii) the localization phenomena in multilayer structures with nanoparticles when the electron mean free path is compared to the interatomic distance (Fig. 2).
