What is it about?
Even when only one photon mode is considered in a cavity, an exact description of the electron-photon interactions is necessary to predict the long-time evolution of an open system with certain geometry. Both the para- and dia-magnetic parts of the interaction are necessary.

Why is it important?
The geometry or the shape of a nanoscale electron system and the cavity it is placed in are important when predicting their dynamical properties and how the total system approaches a steady-state
Perspectives
For me this work shows that in the future electronic-photonic systems may become very good candidates for precission measurements for the electron-photon interactions. Precision measurements have long since been done in quantum optics on atomic systems, but in these new systems we have the added channel of electron transport. It reminds me that in the past the spectroscopy of quantum dots was immensely enhanced, when transport measurements were added to the optical methods.
