Going Beyond the Cumulant Approximation II:Power Series Correction to Single Particle Green's Function in 1D Holstein Chain
Bipul Pandey, Peter B. Littlewood
Previously, we introduced a method for systematically correcting a quasiparticle green's function via a power series expansion. Here we present an ODE based formalisms of power ser…

Going Beyond the Cumulant Approximation: Power Series Correction to Single Particle Green's Function in Holstein System
Bipul Pandey, Peter B. Littlewood
In the context of a single electron two orbital Holstein system coupled to dispersionless bosons, we develop a general method to correct single particle Green's function using a po…
