Robustness of bipolaronic superconductivity to electron-density-phonon coupling
Chao Zhang
We study bipolaron formation and bipolaronic superconductivity on a square lattice, where electrons couple to both local Holstein phonons via on-site charge density and nonlocal bo…

A comprehensive study of bond bipolaron superconductivity in triangular lattice
Chao Zhang
We employ the diagrammatic Monte Carlo method with a lattice path-integral formulation for both electron and phonon degrees of freedom to investigate the formation and properties o…
