Functional renormalization group for multi-orbital Fermi surface instabilities
Functional renormalization group for multi-orbital Fermi surface instabilities
Technological progress in material synthesis, as well as artificial realization of condensed matter scenarios via ultra-cold atomic gases in optical lattices or epitaxial growth of thin films, is opening the gate to investigate a plethora of unprecedented strongly correlated electron systems. In a large subclass thereof, a metallic state of …
