Type-II Dirac semimetal stabilized by electron-phonon coupling

How lattice degrees of freedom affect the topological properties of electrons remains rarely explored. Here, Moeller et al. predict non-trivial topological effects in long-lived polaron bands by studying a two-dimensional model stabilized by realistic electron-phonon coupling.
