| Resumo: | The decoration or iteration transformation were widely applied to solve exactly the magnetic spin models in one-dimensional and two-dimensional lattice. The motif of this Letter is to extend the decoration transformation approach for models that describe interacting electron systems instead of spin magnetic systems, one illustrative model to be studied, will be the spinless fermion model on diamond chain. Using the decoration transformation, we are able to solve this model exactly. The phase diagram of this model was explored at zero temperature as well as the thermodynamic properties of the model for any particle density. The particular case when particle–hole symmetry is satisfied was also discussed. |
