Electron-phonon interaction in the strongly correlated systems and its implications on the high Tc cuprates

Understand

The theory of electron-phonon interaction in the presence of strong correlation has been investigated in the present work.

• Due to the so called spin-charge separation, it is argued that the electron-phonon interaction in the strongly interacting systems is fundamentally different from the weakly interacting counterparts.
• Both spinons and holons are shown to carry electric charge and couple to the electromagnetic field and consequently to phonons.
• A systematic approach to calculate the dynamical charge of spinons and holons is presented, followed by a discussion of implications of this model for the high temperature superconductors.
