Entropy of fermionic models on highly frustrated lattices

Spinless fermions on highly frustrated lattices are characterized by the lowest single-particle band which is completely flat. Concrete realizations are provided by the sawtooth chain and the kagom'e lattice. For these models a real-space picture is given in terms of localized states. Furthermo...
