Conserving approximation for the three-band Hubbard model: Flat quasiparticle dispersion.
It is shown that the low-energy single-particle excitation-spectrum of the three-band Hubbard model at hole-dopings away from half-filling agrees remarkably well with Quantum Monte Carlo data and spectroscopic experiments within the framework of a conserving approximation that includes selfconsistently the interaction with charge, spin, and two-particle fluctuations. The dispersion of the quasi...
متن کاملRandom Dispersion Approximation for the Hubbard model
We use the Random Dispersion Approximation (RDA) to study the Mott-Hubbard transition in the Hubbard model at half band filling. The RDA becomes exact for the Hubbard model in infinite dimensions. We implement the RDA on finite chains and employ the Lanczos exact diagonalization method in real space to calculate the ground-state energy, the average double occupancy, the charge gap, the momentum...
متن کاملQuasiparticle dispersion of the 2D Hubbard model: From an insulator to a metal.
On the basis of Quantum-Monte-Carlo results the evolution of the spectral weight A(k, ω) of the two-dimensional Hubbard model is studied from insulating to metallic behavior. As observed in recent photoemission experiments for cuprates, the electronic excitations display essentially doping-independent features: a quasiparticle-like dispersive narrow band of width of the order of the exchange in...
متن کاملMagnetic properties of the three-band Hubbard model
We present magnetic properties of the three-band Hubbard model in the paraand antiferromagnetic phase on a hypercubic lattice calculated with the Dynamical Mean-Field Theory (DMFT). To allow for solutions with broken spin-symmetry we extended the approach to lattices with AB-like structure. Above a critical sublattice magnetization md ≈ 0.5 one can observe rich structures in the spectral-functi...
متن کاملElectronic properties of the three - band Hubbard model
We study the electronic band-structure and transport properties of a CuO2-plane within the three-band Hubbard model. The Dynamical Mean-Field Theory (DMFT) is used to solve the many particle problem. The calculations show that the optical gap ∆opt is given by excitations from the lower Hubbard band into the so called Zhang-Rice singlet band. The optical gap ∆opt turns out to be considerably sma...
