High-energy kink in the single-particle spectra of the two-dimensional hubbard model.
Employing dynamical cluster quantum Monte Carlo calculations we show that the single-particle spectral weight A(k,omega) of the one-band two-dimensional Hubbard model displays a high-energy kink in the quasiparticle dispersion followed by a steep dispersion of a broad peak similar to recent angle-resolved photoemission spectroscopy results reported for the cuprates. Based on the agreement betwe...
متن کاملAngle-resolved photoemission in high Tc cuprates from theoretical viewpoints
The angle-resolved photoemission (ARPES) technique has been developed rapidly over the last decay, accompanied by the improvement of energy and momentum resolutions. This technique has been established as the most powerful tool to investigate the high Tc cuprate superconductors. We review recent ARPES data on the cuprates from a theoretical point of view, with emphasis on the systematic evoluti...
متن کاملSpectral Properties of Underdoped Cuprates
In the framework of the planar t-J model for cuprates we analyze the development of a pseudo gap in the density of states, which at low doping starts to emerge for temperaturesT < J and persists up to the optimum doping. The analysis is based on numerical results for spectral functions obtained with the finite-temperature Lanczos method for finite two-dimensional clusters. Numerical results are...
متن کاملHole-density evolution of the one-particle spectral function in doped ladders
The spectral function A(q,v) of doped t-J ladders is presented on clusters with up to 2320 sites at zero temperature applying a recently developed technique that uses up to ;6310 rung-basis states. Similarities with photoemission results for the two-dimensional cuprates are observed, such as the existence of a gap at (p ,0) near half-filling ~caused by hole pair formation! and flat bands in its...
متن کاملBCS-like Bogoliubov quasiparticles in high-T(c) superconductors observed by angle-resolved photoemission spectroscopy.
We performed high-resolution angle-resolved photoemission spectroscopy on triple-layered high-T(c) cuprate Bi(2)Sr(2)Ca(2)Cu(3)O(10+delta). We have observed the full energy dispersion (electron and hole branches) of Bogoliubov quasiparticles and determined the coherence factors above and below E(F) as a function of momentum from the spectral intensity as well as from the energy dispersion based...
