Selective Vibronic Excitation for Coherent Energy Transport in Photosynthetic and Agrivoltaic Systems

Steve Cabrel Teguia Kouam, Theodore Goumai Vedekoi, Jean-Pierre Tchapet Njafa +2

Partitioning the photonic environment into resonant and off-resonant modes provides a mechanism for dephasing suppression in photosynthetic energy transfer. Aligning the excitation…

Lagrangian Homotopy Analysis Method using the Least Action Principle

Gervais Nazaire Chendjou Beukam, Jean Pierre Nguenang, Stefano Ruffo +1

The Homotopy Analysis Method (HAM) is a powerful technique which allows to derive approximate solutions of both ordinary and partial differential equations. We propose to use a var…
