Influence of Oxygen Phonon Coupling on Fluctuating Stripes in the Three-band Hubbard Model
ORAL
Abstract
The normal state of high-Tc cuprate superconductors is characterized by competition between multiple ordered states such as antiferromagnetism, charge-density-waves, and stripes. We use determinant quantum Monte Carlo (DQMC) simulations of the three-band Hubbard model with oxygen phonon coupling to investigate how electron-phonon coupling influences high-temperature fluctuating stripes, in relation to doping level, phonon properties and electron-phonon coupling strength. Quantities such as the spin-spin and density-density correlation functions are extracted from the simulations to illustrate the influence of electron-phonon coupling on stripes.
