DESCRIPTION:Speakers: Carmine Ortix ( Institute for Theoretical Physics\, 
 Utrecht University &  Physics Department “E. R. Caianiello”\, Universi
 ty of Salerno)\nNanostructures are material structures with size in the ra
 nge of one to a few hundreds of nanometers in at least one spatial dimensi
 on. They include zero-dimensional quantum dots\, one-dimensional quantum w
 ires and two-dimensional quantum wells. Apart from these conventional mate
 rial geometries\, recent advances in nanostructuring techniques have enabl
 ed the synthesis of complex nanoarchitectures: constructs of one- or two-d
 imensional nanostructures assembled in curved geometries\, such as nanotub
 es and nanohelices. \n\nIn this talk\, I will first show how the very fund
 amental quantum mechanical properties of the charge carriers in these nano
 materials are strongly affected by the curved background in which they liv
 e. Then I will discuss examples of unique curvature-induced topological an
 d transport properties\, including the ballistic anisotropic magnetoresist
 ance effect in non-magnetic and spin-orbit free materials rolled-up into t
 ubes\, and the generation of topological insulating phases in corrugated n
 anowires  with Rashba spin-orbit interaction.\n\nhttps://indico.knu.ua/eve
