Light bipolarons in a system of electrons coupled to dispersive optical phonons

K Kovač, J Bonča - Physical Review B, 2024 - APS
We investigate the ground-state properties of the bipolaron coupled to quantum dispersive
optical phonons in the one-dimensional Holstein-Hubbard model. We concentrate on the …

Spectral function of a bipolaron coupled to dispersive optical phonons
