We investigate the properties of composite polaron containing the effects of electron-phonon coupling and interaction between impurity and electron-hole pair. A model of a two-dimensional electron gas occupying the surface of two-dimensional Dirac honeycomb lattice is constructed. We focus on the weak coupling regime throughout the whole paper. Our results are meaningful to the study of pairing mechanism as well as the phonon-mediated high-temperature superconductivity.

  1. Attractive polaron formed in doped nonchiral/chiral parabolic system within ladder approximation

    cond-mat.quant-gas 2019-08 reject novelty 4.0 of 10

    For a chiral parabolic band, the polaron self-energy and pair propagator are claimed to depart strongly from the nonchiral case at low momentum, producing instabilities that disappear at large momentum.
