Claims

C1strongest claim

Using sign-problem-free quantum Monte Carlo simulations of a bond-Peierls model on the square and cubic lattices, a dilute liquid of such bipolarons forms an s-wave superconductor with a Tc/Ω that significantly exceeds the conventional bound, that this conclusion is robust against screened Coulomb repulsion, and that Tc/Ω remains above the bound in presence of strong long-range Coulomb repulsion.

C2weakest assumption

The premise that bipolarons formed by phonon-modulated hopping remain sufficiently light and mobile to condense into a dilute superconducting liquid at the simulated densities and couplings, rather than localizing or becoming heavy as in Holstein models; this enters via the instanton analysis and QMC results on specific lattices.

C3one line summary

In Peierls electron-phonon models, small but light bipolarons form a dilute s-wave superconductor with Tc/Ω exceeding the Migdal-Eliashberg bound, as shown by sign-problem-free QMC simulations that remain robust to Coulomb repulsion.
