Self-consistent Born approximation for the hole motion in the three-band model: A comparison with photoemission experiments.

چکیده
The dispersion relation of the single hole in CuO2 plane is calculated in the self-consistent Born approximation for the thee-band Hamiltonian. We find that direct oxygen-oxygen hopping removes the strong anisotropy of the hole spectrum around the band minima. Our results compare well with recent photoemission measurements of single hole dispersion relation in the Sr2CuO2Cl2. PACS: 71.25.-s, 71.27.+a, 79.60.Bm

One-particle spectral weight of the three-dimensional single-band Hubbard model.
Dynamic properties of the three-dimensional single-band Hubbard model are studied using quantum Monte Carlo combined with the maximum entropy technique. At half-filling, there is a clear gap in the density of states and well-defined quasiparticle peaks at the top ~bottom! of the lower ~upper! Hubbard band. We find an antiferromagnetically induced weight above the naive Fermi momentum. Upon hole...

The electronic properties of YBa2Cu3O7-δ have been investigated by the energy-pseudopotential method within the local density approximation (LDA) with and without including generalized gradient corrections (GGC). The band structure, density of states and charge density of YBa2Cu3O7- have been calculated. The results are compared with other approaches such as LAPW, LCAO and LMTO for this syste...
متن کاملQuasiparticle photoemission intensity in doped two-dimensional quantum antiferromagnets
Using the self-consistent Born approximation, and the corresponding wave function of the magnetic polaron, we calculate the quasiparticle weight corresponding to destruction of a real electron (in contrast to creation of a spinless holon), as a funtion of wave vector for one hole in a generalized t − J model and the strong coupling limit of a generalized Hubbard model. The results are in excell...
متن کاملTesting variations of the GW approximation on strongly correlated transition metal oxides: hematite (α-Fe2O3) as a benchmark.
Quantitative characterization of low-lying excited electronic states in materials is critical for the development of solar energy conversion materials. The many-body Green's function method known as the GW approximation (GWA) directly probes states corresponding to photoemission and inverse photoemission experiments, thereby determining the associated band structure. Several versions of the GW ...

We studied the architecture of the C60 cluster to drive its atomic positions which can be seen at room temperature. We then used the obtained carbon positions as a basis set for the fcc structure to construct the fcc-C60 compound. Self consistent calculations were performed based on the density functional theory (DFT) utilizing the accurate WIEN2K code to solve the single-particle Kohen-Sham eq...
