The lecture "Flat Bands and Localized Flat-Band States in SQUID Lieb Metamaterials" will be held in NUST MISIS, lecture hall № Б-708 (7th floor) on 25th of April 2017 at 13:00 by Nikolaos Lazaridis (Crete University, Greece).
Abstract: The concepts related to flat bands in condensed matter systems as well as recent experiments in optical Lieb and Kagome lattices in two dimensions are overviewed. Emphasis is given to the physical consequences arising from flat bands such as the vanishing dispersion, and the localization of flat-band modes. SQUID metamaterials are introduced and their most important properties are discussed. Then, a SQUID metamaterial on a Lieb lattice is presented, and its dynamic equations as well as its linear frequency spectrum, which contains a flat band, are obtained. The conditions for localized flat band states in that system are discussed.
