There have been substantial theoretical advances in the field of condensed matter physics in recent years. These significant developments have spanned many different principles. For example, accelerated research into understanding how quantum field theory is connected to physics has attracted a lot of attention from other domains. In particular, exciton and magnetoexciton coupled systems are popular due to their compatibility with experimental research. This study investigated and presented a theoretical description of electron-hole–photon interactions and excitonization in a microcavity nano-quantum environment based on QED, QFT, and quanto-relativistic behavior of the electron-hole coupled system. This work represents conversion, a main theoretical and applied physics subject, including electronic technologies, electro-photo catalysts, super batteries capacitors, qubits, quantum computation, and magneto-excitonic solar cells. The quanto-relativistic mass and the coupled electron-hole systems were investigated using the Rytova-Keldysh and Coulomb potential in a free exciton system. The ground and excited coupled state energy and mass of free exciton as an atomic system in the oscillator explanation of a symplectic group were determined. This projective method is in line with other theoretical methods and could be useful to study and predicate several different multi-excitons exotic systems and determine the angular velocity of exotic coupled states and relativistic mass of particles, which is important in mono elemental or non-mono elemental nanolayers materials.
