Temperature-Driven Sequential Modeling for the Prediction of Annual Power Conversion Efficiency Profiles of Organic Photovoltaic Materials: Douala Case Study
Steve Cabrel Teguia Kouam, Rockefeller Rockefeller, Raoult Dabou Teukam +4
Organic photovoltaic (OPV) materials are promising candidates for distributed solar energy in tropical regions, yet existing virtual screening tools report static power conversion…
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…
Comparative Analysis of GFN Methods in Geometry Optimization of Small Organic Semiconductor Molecules: A DFT Benchmarking Study
Steve Cabrel Teguia Kouam, Jean-Pierre Tchapet Njafa, Raoult Dabou Teukam +3
This study benchmarks the GFN family of semiempirical methods (GFN1-xTB, GFN2-xTB, GFN0-xTB, and GFN-FF) against density functional theory (DFT) for the evaluation of optimized mol…
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…
Fractional Dynamics and Modulational Instability in Long-Range Heisenberg Chains
Laetitia Mbetkwe Youwa, Jean Pierre Nguenang, Paul André Paglan +3
We study the effective dynamics of ferromagnetic spin chains in presence of long-range interactions. We consider the Heisenberg Hamiltonian in one dimension for which the spins are…
Fermi-Pasta-Ulam chains with harmonic and anharmonic long-range interactions
G. N. B. Chendjou, J. P. Nguenang, A. Trombettoni +3
We study the dynamics of Fermi-Pasta-Ulam chains with both harmonic and anharmonic power-law long-range interactions. We show that the dynamics is described in the continuum limit…
