Cumulant expansion in the Holstein model: Spectral functions and mobility

Petar Mitrić, Veljko Janković, Nenad Vukmirović +1

We examine the range of validity of the second-order cumulant expansion (CE) for the calculation of spectral functions, quasiparticle properties, and mobility of the Holstein polar…
