Instability due to long range Coulomb interaction in a liquid of polarizable particles (polarons, etc.)
J. Lorenzana
The interaction Hamiltonian for a system of polarons a la Feynman in the presence of long range Coulomb interaction is derived and the dielectric function is computed in mean field…

Dynamics of the 1D Heisenberg model and optical absorption of spinons in cuprate antiferromagnetic chains
J. Lorenzana, R. Eder
We use numerical and analytical results to construct a simple ansatz for the energy dynamical correlation function of the 1D antiferromagnetic Heisenberg model. This is applied to…

Phonon Assisted Multimagnon Optical Absorption and Long Lived Two-Magnon States in Undoped Lamellar Copper Oxides
J. Lorenzana, G. A. Sawatzky
We calculate the effective charge for multimagnon infrared (IR) absorption assisted by phonons in the parent insulating compounds of cuprate superconductors and the spectra for two…
