Colloidal crystals are arguably one of the most promising candidates when it comes to fabrication nanostructured metamaterials. Especially mesocrystals show exciting new properties that emerge from their inherent directional oriented assembly. With this work, electrical conductivity well-defined micrometer-sized platinum nanocube-based is demonstrated and tuned through variation different cappi...

Twisted bilayer graphene displays many fascinating properties that can be tuned by varying the relative angle (also called twist angle) between its monolayers. As a remarkable feature, both electronic flat bands and corresponding strong electron localization have been obtained at specific "magic" ($\sim 1.1^{\circ}$), leading to observation of several strongly correlated phenomena. Such discove...
