Peierls Coupling in Multi-Orbital Superconducting Oxides

Event Information:

We study the eﬀects of the Peierls electron-phonon coupling in diﬀerent multi-band systems. In contrast to the more commonly employed Holstein coupling, which is used in single-band models and is momentumindependent, the momentum-dependent Peierls coupling can explicitly treat coupling to multiple bands. Our results demonstrate the importance of using the Peierls coupling in modelling complex systems
