- Descripción
- A generalized <math>tJ\,\!</math> Hamiltonian is analyzed within the framework of a quantum real space renormalization group. Besides the usual hopping <math>(t)\,\!</math>, exchange <math>(J)\,\!</math> and chemical potential <math>(\mu )\,\!</math> terms the Hamiltonian contains a nearest-neighbor charge interaction one and is in variant under the renorinalization. The finite temperature phase diagram of the <math>d = 2\,\!</math> and <math>d = 3\,\!</math> model is calculated in the full range of the parameters. Our results show that many of the critical properties of the La and <math>Y\,\!</math> based high-<math>T_c\,\!</math>, superconductors can be explained by the present model.
