Phonon effects, impact ionization and power conversion in Mott photovoltaic systems
Paolo Gazzaneo, Enrico Arrigoni
We analyze the effect of acoustic phonons on the photocurrent and the spectral characteristics of a simplified photovoltaic setup made of Mott insulating layers between two metalli…

Numerically exact simulation of photo-doped Mott insulators
Fabian Künzel, André Erpenbeck, Daniel Werner +4
A description of long-lived photo-doped states in Mott insulators is challenging, as it needs to address exponentially separated timescales. We demonstrate how properties of such s…
