Doping dependence of density response and bond-stretching phonons in cuprates
We explain the anomalous doping dependence of zone boundary (π, 0) and (π, π) bond-stretching phonons in La2−δSrδCuO4 in the range 0 < δ < 0.35. Our calculations are based on a theory for the density response of doped Mott-Hubbard insulators.
متن کاملCharge dynamics of t-J model and anomalous bond-stretching phonons in cuprates
The density response of a doped Mott-Hubbard insulator is discussed starting from the t-J model in a slave boson 1/N representation. In leading order O(1) the density fluctuation spectra N(q,ω) are determined by an undamped collective mode at large momentum transfer, in striking disagreement with results obtained by exact diagonalization, which reveal a very broad dispersive peak, reminescent o...
متن کاملDensity Response of Cuprates and Renormalization of Breathing Phonons
We analyse the dynamical density fluctuation spectra for cuprates starting from the t− J model in a slave-boson 1/N representation. The results obtained are consistent with diagonalization studies and show novel low-energy structure on the energy scale J + δt due to the correlated motion of holes in a RVB spin liquid. The low-energy response implies an anomalous renormalization of several phono...
متن کاملDoping dependence of the electronic Raman spectra in cuprates
We report electronic Raman scattering measurements on Bi2Sr2(Y1−xCax)Cu2O8+δ single crystals at different doping levels. The dependence of the spectra on doping and on incoming photon energy is analyzed for different polarization geometries, in the superconducting and in the normal state. We find the scaling behavior of the superconductivity pair-breaking peak with the carrier concentration to ...
متن کاملDoping and temperature dependence of incommensurate antiferromagnetism in underdoped lanthanum cuprates
The doping, temperature and energy dependence of the dynamical spin structure factors of the underdoped lanthanum cuprates in the normal state is studied within the t-J model using the fermion-spin transformation technique. Incommensurate peaks are found at [(1±δ)π, π], [π, (1±δ)π] at relatively low temperatures with δ linearly increasing with doping at the beginning and then saturating at high...
