This workshop brought together experts in condensed matter physics to discuss recent advances in the field of flat band systems. The topics include flat band physics in geometrically frustrated lattices; systematic search of flat band materials; correlation-induced flat bands and flat band-induced correlations; charge, heat and thermoelectric  transport in flat band metals.
