 "In one of the first theoretical papers considering lattice vibrations in cuprates the phonon softening was found by exact diagonalization technique in the model where effective Hamiltonian was obtained from the threeband model [162]. Softening of the breathing q = (π, π) and halfbreathing q = (π, 0) phonons was calculated in [83] [84] [87] [92]. The calculation predicted dependence of the softening on the doping concentration which was later confirmed experimentally [95]. "

ABSTRACT: A review of experimental and theoretical results on the spectroscopy of hightemperature superconductors is presented. The models where hole doped into antiferromagnet interacts both with magnetic subsystem and with phonons are considered. Theoretical results of these models for phonon spectra, angle resolved photoemission spectra, and optical conductivity are presented. Comparison with experimental data gives evidence for the strong electronphonon coupling in the undoped and weakly doped hightemperature superconductors. The strength of electronphonon coupling decreases with doping though at the optimal doping the compounds are still in the intermediate coupling regime.Advances in Condensed Matter Physics 01/2010; 2010(16878108).

ABSTRACT: We examine the singleparticle excitation spectrum in the onedimensional HubbardHolstein model at halffilling by performing the dynamical density matrix renormalization group (DDMRG) calculation. The DDMRG results are interpreted as superposition of spectra for a spinless carrier dressed with phonons. The superposition is a consequence of robustness of the spincharge separation against electronphonon coupling. The separation is in contrast to the coupling between phonon and spin degrees of freedom in twodimensional systems. We discuss implication of the results of the recent angleresolved photoemission spectroscopy measurements on SrCuO${}_{2}$.

ABSTRACT: Momentum and doping dependence of the static charge susceptibility \chi(q) in the tt'J model is investigated. Correlations lead to a strongly momentum dependent renormalization of \chi(q). The charge susceptibility near (\pi,\pi) region of the Brillouin zone is strongly suppressed as the hole density \delta is decreased. However, contrary to naive expectations, \chi(q) around q = (\pi,0) and (0,\pi) remains large and practically unchanged at \delta \sim 0.10.5. This effect is consistent with a tendency towards lowenergy charge fluctuations with the wave vectors along the \GammaX direction, reported in earlier studies. Our main finding is that the above trends are amplified by Jdriven pairing effects, indicating that the pseudogap formation may promote the charge inhomogeneity. The nextnearest hopping t' leads to weakening of the above momentumselective renormalizations of \chi(q). We analyze the effects of longrange Coulomb interaction, taking into account a layered structure of cuprates. As an application, the results are discussed in the context of bondstretching phonon softening in holedoped cuprates. In particular, a peculiar doping and momentum dependence of the electronphonon coupling constant is found.Physical review. B, Condensed matter 04/2006; 74(4).
