The quest for materials and materials systems which show novel functionalities and newly emergent electronic states or phenomena is strongly triggered by the ever advancing fields of nano- and quantum-technologies and their according requirements in terms of integration or quantum coherence. This has driven research to consider different approaches to achieve such novel states ranging from synthesis of novel materials, the chemical derivation of existing materials or exposure to external fields. Here we will present two examples: metasurfaces of germanium nanohelices, a structurally chiral semiconductor, and graphene, hosting a prototype Weyl-like fermionic system, and show how combination of cooperativity, nanostructuring, external fields, and physical derivation can lead to novel material’s functionalities and the emergence of unconventional states.
