Abstract The paper presents a theoretical model of the AU field as a unified gauge structure combining dark energy, non-local correlations, consciousness, and gravity. An axiomatic Lagrangian is developed, describing the dynamics of the AU field, consciousness field, entropy field, and their interactions with matter. The research demonstrates the self-consistency of classical field theory when considering the dynamic nature of the entropy field. Key experimental predictions are identified: violation of the equivalence principle, anomalous polarization plane rotation, non-local correlations in biophoton experiments, and variation of fundamental constants. The work significantly contributes to understanding fundamental interactions by proposing a new approach to unifying quantum mechanics, gravity, and consciousness within a single theoretical framework. Key words: AU field, dark energy, consciousness field, non-local correlations, modified gravity, quantum field theory, entropy field, cosmological constant, quantum fluctuations, phase transitions. The main results of the study are as follows: A closed system of equations for the AU field, the consciousness field, and the entropy field has been constructed. The analysis of quantum corrections in the weak field approximation has been conducted. The stability of the vacuum and possible phase transitions have been investigated. Experimentally verifiable predictions of the theory have been identified. The possibility of combining various physical phenomena within a single model is demonstrated.
