Abstract
The interplay between band and atomic aspects in materials with co-existing wide-band and flat-band states, or wide-band and effectively dispersionless electronic states is increasingly expected to lead to novel behavior. Using dynamical mean-field theory (DMFT), we investigate strange-metal-like behavior and emergence of unconventional superconductivity in a toy model that captures this interplay. Surprisingly, we find good accord with transport features seen in underdoped cuprates and ladder Fe-arsenides. We connect our findings to proposals of FL and orthogonal Fermi liquids, and present a route to it's direct instability to novel, competing orders.
