Entropy of fermionic models on highly frustrated lattices
A. Honecker, J. Richter
Spinless fermions on highly frustrated lattices are characterized by a lowest single-particle band which is completely flat. Concrete realizations are provided by the sawtooth chai…

Jordan-Wigner approach to the frustrated spin one-half XXZ chain
T. Verkholyak, A. Honecker, W. Brenig
The Jordan-Wigner transformation is applied to study the ground state properties and dimerization transition in the chain. We consider different solutions of the me…
