Effects of phonon dispersion on the bond-bipolaron superconductivity
Chao Zhang, Nikolay Prokof'ev, Boris Svistunov
We employ the diagrammatic Monte Carlo method based on lattice path-integral representaion of the particle sector and real-space diagrammatics of the phonon sector to study effects…

Superfluid transition of bond bipolarons with long-range Coulomb repulsion in two dimensions
Chao Zhang
Using numerically exact diagrammatic Monte Carlo simulations in the two-electron (single-bipolaron) sector, we explore the impact of long-range Coulomb repulsion on the dilute-limi…
