The quantum vacuum beneath the aromatic ring: How QED shapes Benzene

Benzene, one of the most critical molecules in aromatic chemistry, was previously interpreted through frameworks such as Molecular Orbital Theory without realistic quantum scrutiny. This research attempts to present a novel interpretation by uniquely connecting different fields, elucidating the benzene molecule from the perspective of Quantum Electrodynamics (QED). The paper provides an interpretation of benzene starting from the fundamental particles of the universe, like quarks and gluons, through the formation of the nucleus and electrons, the electron-electron interactions via the S-matrix, and the interactions of particles with the surrounding electromagnetic field in the vacuum. This extends to the formation of the benzene molecule and its bonds, the transition from individual vibrations to a collective vibration mode, and the interpretation of the 2pz bonds between the electrons of each carbon atom. It details how they continuously exchange virtual photons, maintaining constant mutual repulsion, alongside their continuous interactions with the ambient virtual photons in the electromagnetic field. and explore their integration into a PZW polarization field, where all Electrons move collectively during a single interaction. Additionally, it examines the formation of a natural cavity of benzene and its effect on the surrounding electromagnetic field, clarified through the Hamiltonian. Finally, it addresses the formation of the polaritonic state of benzene, demonstrating that by tuning the targeted electromagnetic field frequencies in a specific region, a vibrational polariton occurs. This leads to practical scientific applications, illustrated by empirical graphs, such as the modulation of reaction rates and the impact of polariton formation compared to ordinary benzene outside a cavity. This provides compelling theoretical and numerical evidence highlighting the main role of Quantum Electrodynamics in interpreting the structural and reactive properties of benzene.
