# Pseudomode approach and vibronic non-Markovian phenomena in light harvesting complexes

## TL;DR

This paper explores the pseudomode approach's theoretical foundations and its application to non-Markovian vibronic phenomena in light-harvesting complexes, with extensions to finite-temperature scenarios.

## Contribution

It connects the pseudomode approach with well-known quantum models and applies it to describe non-Markovian effects in biological complexes.

## Key findings

- Connection established between pseudomode approach and Friedrichs/Jaynes-Cummings models
- Application to Fenna-Matthews-Olson complexes with experimental estimations
- Discussion on extending the approach to finite temperatures

## Abstract

The pseudomode approach is discussed with an emphasis to Gorini-Kossakowski-Sudarshan-Lindblad form of this approach. The connection of the pseudomode approach with solutions of both the Friedrichs model and Jaynes-Cummings model with dissipation at zero temperature is shown. The obtained results are applied to non-Markovian phenomena description in the Fenna-Matthews-Olson complexes, estimations based on experimental data are done. A deformation approach to generalization of the pseudomode approach to the finite-temperature case is discussed.
