Geometry- and Topology-Controlled Nanoarchitectures
Session proposed by the EPS-CMD Structure and Dynamics Section
A highly diversified study of topological matter is one of the fascinating main roads of modern physics. The realm of topological matter can be conventionally subdivided in two parts. First, non-trivial topology occurs due to a special geometry of structures or fields in real space, e.g., quantum rings, Möbius bands, multi-terminal Josephson junctions, Skyrmions. Second, topologically protected surface/edge states governed by Dirac physics and/or topologically nontrivial electronic structure in the momentum space underlie Quantum Hall effect, topological insulators, superconductors, semimetals. The present Contributed Session will be focused on the interplay between those two realms. An overview will be given about topology- and geometry-driven effects, owing to special geometries of novel micro- and nanoarchitectures fabricated of both conventional and topologically nontrivial materials implemented by the high-tech techniques, in particular, strain-driven self-organization. It is planned to  demonstrate how topology and complicated geometry of various quantum fields (electron (hole), spin, photon, phonon, plasmon…) determine the physical properties of emerging nanostructured materials leading to their functionalization towards novel applications in advanced nanotechnologies, including quantum optical information processing, superconductor elements for fluxonics, THz-emitters, thermo-power couplers, flexible thin-film sensors, dissipationless electronic and spintronic components, plasmonic waveguides for biomedical diagnostics, manipulation of photons in on-chip quantum devices.
